c. Dermis

(Std 9 – Human Body Organ System)

The skin is like an envelope and its complex structure is divided into three layers of tissues: 1.Epidermis 2.Dermis 3.Hypodermis

Epidermis is the upper layer of the skin. The outermost layer consists of flat, thin and scale – like dead cells. It is separated from the dermis by the basement membrane.

The dermis is the middle layer. It is thick but elastic. The dermis consists of nerves, blood vessels, hair follicles, sweat glands and sebaceous glands (oil glands). Sweat glands separate sweat from the blood.

It is the innermost layer of the skin. It is thick and contains large amounts of adipose tissue.

(Std 10 – Chemical Reaction)

The chemical reactions which take place with the evolution of heat energy are called exothermic reactions.

 d. 60 kmph

Distance = 1 km ,

Speed x   = 120 km/hr

Speed y   = 40 km/hr

Average Speed = (2 * x * y) / (x + y) [ie Same Distance]

 Average Speed = Total Distance / Total Time  [ie Different Distance]

Here the distance is same. So,

Average Speed = (2 * x * y) / (x + y)

                                            = (2 * 120 * 40) / 160

                                            = 60 km / hr

                   Answer => 60 km / hr

Unit digits of 3 :

            3⁰ = 1, 3¹ = 3, 3² = 9, 3³ = 7, 3⁴ = 1, 3⁵ = 3, 3⁶ = 9, 3⁷ = 7…………

To find the unit digit of 3⁶⁵,

                                    (65 / 4) => Remainder = 1

                                          3¹   = 3,

So, unit digit of 3⁶⁵ value is       = 3

Unit digits of 6 :

6⁰ = 1, 6¹ = 6, 6² = 6, …….

6 ^{Any number} = 6 (other than 6⁰)

Here, unit digit of 6⁵⁹ = 6

Unit digits of 7 :

            7⁰ = 1, 7¹ = 7, 7² = 9, 7³ = 3, 7⁴ = 1, 7⁵ = 7, 7⁶ = 9, 7⁷=3,……….

To find the unit digit of 7⁷¹,

                                    71 / 4 => Remainder 3

                                     7 / 3  = 3

So, unit digit of 7⁷¹     = 3

Unit digit in the product of 3⁶⁵ * 6⁵⁹ * 7⁷¹,

                                                = 3 * 6 * 3

                                                = 4

Unit digit in the product of 3⁶⁵ * 6⁵⁹ * 7⁷¹ => 4

C. 4

If a number is divisible by 3, 9, 10 means, it is divisible by 90.

If a number is divisible by 9, it can be divisible by 3 also.

So, only check if a number is divisible by 9 and 10.

            Here, 653 * y ÷ 90,

From the option,

                        x + y = 4,

            6 + 5 + 3 + 4  = 18 (divisible by 9)

                             x   = 4

                             y   = 0

               65340 ÷ 90

So,     x + y = 4

C. 2

If the sum of the digits of a number is divisible by 3. Then the number is divisible by 3.

Here,

            517*324 is divisible by 3,

So,

            5 + 1 + 7 + 3 + 2 + 4  = 22

The smallest whole number in the place of * is = 2.

          22 + 2 = 24 divisible by 3.

          Answer => 2

b. Suryavarman II

(Std 11 – The Spread of Indian Culture in Other Asian Countries)

Yasovarman and Suryavarman II were two well-known rulers of Kambhoja kingdom (Cambodia). Here Temples were built in South Indian style. There are plenty of Sanskrit inscriptions.

Congress launched the Civil Disobedience Movement in 1930. As a part of it, Gandhi led the Salt Satyagraha (Dandi march) in March 12, 1930. The British convened the First Round Table Conference in Nov 1930. No one from INC attended it and hence it was not successful.

Gandhi-Irwin Pact was signed in March 1931 and hence Gandhi accepted the invitation of British to attend the Second Round Table Conference (Sep to Dec 1931).

Disappointed with the issue of Communal Award, Gandhi again started the Civil Disobedience Movement after returning from Second Round Table Conference (London). Hence no one from INC attended the Third Round Table Conference (Nov to Dec 1932)

d. Water and Jobs

World Water Day dates back to the 1992 United Nations Conference on Environment and Development where an international observance for water was recommended. The United Nations General Assembly responded by designating 22 March 1993 as the first World Water Day.

Today, almost half of the world’s workers – 1.5 billion people – work in water related sectors and nearly all jobs depend on water and those that ensure its safe delivery. Yet the millions of people who work in water are often not recognized or protected by basic labour rights. The theme in 2016 — water and jobs — is focusing on how enough quantity and quality of water can change workers’ lives and livelihoods – and even transform societies and economies.

a. Rs.40

A’s 1 day work  = 1 / 5

B’s 1 day work  = 1 / 10

A + B + C’s 1 day work   = 1 / 2

To find C’s 1 day work,

(1 / A) + (1 / B) + (1 / C) = 1/ 2

           (1 / C)   = (1 / 2) – [(1 / A) + (1 / B)]

= (1 / 2) – [(1 / 5) + (1 / 10)]

LCM of 2, 5, 10 = 10

= (5 – 2 – 1) / 10

= (2 / 10)

C’s 1 day work            => (1 / 5)

To find the ratio of their 1 day’s work,

                A : B : C = (1 / 5) : (1 / 10) : (1 / 5)

LCM of 5, 10, 5 is 10

So,  A : B : C = 2 : 1 : 2

Here total part is 5.

Total share = 100

C’s share = (2 / 5) * 100

= 40

       C’s share  => 40
