Question 1 of 8

1. Question

Three circles of equal radii touch each other as shown in the figure given below. The radius of each circle is 2 cm. What is the area of the shaded region?

Correct

Area of the triangle= √3/4 * 4² = 4√3

Area of 3 circles enclosed by the triangle= 3*π* 2²* 60/360 = 2π

Area of the shaded region= 4√3 – 2π = 2 (2√3 – π) cm²

Incorrect

Area of the triangle= √3/4 * 4² = 4√3

Area of 3 circles enclosed by the triangle= 3*π* 2²* 60/360 = 2π

Area of the shaded region= 4√3 – 2π = 2 (2√3 – π) cm²

Question 2 of 8

2. Question

The ratio of the cost price to the marked price of an article is 2:3 and the ratio of the percentage profit to the percentage discount is 3:2. What is the discount percentage?

Correct

Ratio of CP: MP= 2x: 3x

Profit= x

The ratio of % profit: % discount= 3:2

Cp= 200 SP= 300

3x/100*200 + 2x/100* 300= 100

6x + 6x= 100

X= 100/12= 25/3%

Incorrect

Ratio of CP: MP= 2x: 3x

Profit= x

The ratio of % profit: % discount= 3:2

Cp= 200 SP= 300

3x/100*200 + 2x/100* 300= 100

6x + 6x= 100

X= 100/12= 25/3%

Question 3 of 8

3. Question

Babul borrowed Rs. 1200 at 12% rate of interest. He repaid Rs. 500 at the end of the first year. What is the amount required to pay at the end of the second year to discharge his loan which was calculated at compound interest?

Correct

Amount to be paid at the end of 2 years= 1200*12*2/100 + 1200= 1488

Amount left as principal for the second year= 1488-500= 988

Amount to be paid after 2nd year= 988+ 988*12/100= 1106.56

Incorrect

Amount to be paid at the end of 2 years= 1200*12*2/100 + 1200= 1488

Amount left as principal for the second year= 1488-500= 988

Amount to be paid after 2nd year= 988+ 988*12/100= 1106.56

Correct

40* 30* 50 = x * 30 * 20

X= 100

% increase in the no. of pages= 100-40/40 * 100 = 150%

Incorrect

40* 30* 50 = x * 30 * 20

X= 100

% increase in the no. of pages= 100-40/40 * 100 = 150%

Suhani is thrice as efficient as Raima and Raima can do a piece of work in 27 days. Raima started working and after a few days Suhani joined him. They completed the work in 15 days from the beginning. For how many days did they work together?

Correct

Efficiency of Suhani= 3x Raima= x

Raima can do a work in 27 days

Suhani can do a work= 27/3= 9 days

In one day they both work in= 1/27 + 1/9= 4/27

Suhani joined Raima after (15-x) days

15-x/27 + 4x/27 = 1

15 – x + 4x= 27

3x= 12

X= 4

Incorrect

Efficiency of Suhani= 3x Raima= x

Raima can do a work in 27 days

Suhani can do a work= 27/3= 9 days

In one day they both work in= 1/27 + 1/9= 4/27

Suhani joined Raima after (15-x) days

Correct

25t = 30 (t – 2)

25t = 30t – 60

T= 12

Distance= 25*12= 300

Incorrect

25t = 30 (t – 2)

25t = 30t – 60

T= 12

Distance= 25*12= 300

Question 8 of 8

8. Question

From a group of 5 men and 2 women, 2 persons are selected randomly. Find the probability that at least one woman is selected.

Correct

n(S) = 7!/ 2! * 5!

= 7*6*5! / 2*1*5!

= 21

n(E)= 2!/1!*1! * 5! /1!*4! * 2! /2! * 0!

= 2*5 + 1= 11

Req probability= 11/21

Incorrect

n(S) = 7!/ 2! * 5!

= 7*6*5! / 2*1*5!

= 21

n(E)= 2!/1!*1! * 5! /1!*4! * 2! /2! * 0!

= 2*5 + 1= 11

Req probability= 11/21
