Quantity I: Three years before, the ratio of ages of A and B was 5:6. Three years hence this ratio will become 6:7 Quantity

II: Eleven years before the ratio of ages of A and B was 1:3 and eleven years hence the ratio will become 1:2

Correct

Explanation: Quantity I: A, B 3 years before 5, 6

3 years after 6. 7

Difference in both case 6-5=1 and 7-6=1 1=6 6=30

Present age =30+3=33

Quantity II: A B 11 years before 1 3 11 years after 1 2 Difference A=1-1=0 ; B= -1 To make the difference same; multiply equation 2 by 2; we get Quantity II: A B 11 years before 1 3 11 years after 2 4 Difference A=2-1=1; B=4-3=1 1=2 11=22 Present age= 22+11=33

Incorrect

Explanation: Quantity I: A, B 3 years before 5, 6

3 years after 6. 7

Difference in both case 6-5=1 and 7-6=1 1=6 6=30

Present age =30+3=33

Quantity II: A B 11 years before 1 3 11 years after 1 2 Difference A=1-1=0 ; B= -1 To make the difference same; multiply equation 2 by 2; we get Quantity II: A B 11 years before 1 3 11 years after 2 4 Difference A=2-1=1; B=4-3=1 1=2 11=22 Present age= 22+11=33

Question 9 of 15

9. Question

Category: New Pattern Quadratic Equations

Find the sum

Quantity I: If the Compound Interest for 2 years at 20% rate of interest is Rs 1,320.

Quantity II: If the amount on a sum for 2 years in which rate of interest for 3 years makes a sum of 125 to amount 216 is Rs 2880.

Correct

Explanation:

CI for 2 years on 20%=1/5 5 6 5 6 5*5=25 6*6=36 CI=36-25=11 =1320

Quantity I: A man covers a distance in 15 hours. He covers first half at 12 kmph and second half at 15 kmph.

Quantity II: Two buses moves towards each other at a speed of 30 kmph and 40 kmph respectively. When they meet it is found that faster bus covers 30 km more than slower one.

Correct

Explanation:

Average Speed=2*12*15/(12+15) D=S*T = 2*12*15/27 * 15 = 200 KM

Quantity II: Speed difference for 1 hour =40-30=10 Kmph; means in 1 hour faster bus will cover 10 km more than slower one; hence to cover 30 km more it will take 3 hours. Distance= Relative Speed * Time D= 3* (30+40) =210 KM

II > I

Incorrect

Explanation:

Average Speed=2*12*15/(12+15) D=S*T = 2*12*15/27 * 15 = 200 KM

Quantity II: Speed difference for 1 hour =40-30=10 Kmph; means in 1 hour faster bus will cover 10 km more than slower one; hence to cover 30 km more it will take 3 hours. Distance= Relative Speed * Time D= 3* (30+40) =210 KM

II > I
