## A’s 2 days work is equal to B’s 3 days work. If A can complete the work in 8 days, then to complete the work B will take:

### Poll Results

1. Explanation: According to the question, 2A = 3B A\B=3\2 Then efficiency ratio A:B=3:2 We know that time is inversely preportional to efficiency Then time taken by them in ratio ∴A can do the work in 8 days =i.e 2 units → 8 1 unit → 4 = time taken by B → 3 units = 3×4=12 days

Explanation:

According to the question,

2A = 3B

A\B=3\2

Then efficiency ratio A:B=3:2

We know that time is inversely preportional to efficiency

Then time taken by them in ratio

∴A can do the work in 8 days

=i.e 2 units → 8

1 unit → 4

= time taken by B → 3 units

= 3×4=12 days

## A sum of Rs.3200 becomes Rs.3456 in two years at a certain rate of simple interest. What is the rate of interest per annum?

### Poll Results

1. Explanation: Interest = 3456 - 3200 = Rs.256 Therefore, Rate = S.I.×100/Principal×Time =256×100/3200×2 = 4% per annum

Explanation:

Interest = 3456 – 3200 = Rs.256

Therefore, Rate = S.I.×100/Principal×Time

=256×100/3200×2 = 4% per annum

## The difference between the simple interest on a certain sum at the rate of 10% per annum for 2 years and compound interest which is compounded every 6 months is Rs.124.05. What is the principal sum?

### Poll Results

1. Explanation: Let the principal sum be P SI = PRT\100 CI = P [(1+R\100)^nt−1] R = 10 %, T = 2 years, n = 2 [because CI is compounded half yearly] SI = P×10×2\100=P\5 CI = P [(1+10\100×2)^2×2−1] CI = P [(21\20)^4−1] CI = P [194481\160000−1] CI = 34481\16000P CI - SI = 34481\160000 P−P5 = 34481−32000\1Read more

Explanation:

Let the principal sum be P

SI = PRT\100

CI = P [(1+R\100)^nt−1]

R = 10 %, T = 2 years, n = 2 [because CI is compounded half yearly]

SI = P×10×2\100=P\5

CI = P [(1+10\100×2)^2×2−1]

CI = P [(21\20)^4−1]

CI = P [194481\160000−1]

CI = 34481\16000P

CI – SI = 34481\160000 P−P5

= 34481−32000\16000 P

= 2481\160000 P

∴ 2481\16000 P = 124.05

P = 124.05×160000\2481 = Rs.8000

Explanation:

The correct answer is Option 2.

When we put the sentences in order, it is important to establish a connection between them.

The subject ‘Vaikom Muhammad Basheer’ is introduced in line B. The line gives information that he was a Malayalam fiction writer from Vaikom in Kerala.

A follows B. It connects with B, that when the writer returned back from travel, he was forced to live in a house where his large family lived.

D is the following line after A. It describes the large family where myriads of domestic animals also lived in the house and treated the house as their own.

C follows D. Because there were family members and animals, the household was always noisy and full of chaos.

Thus the correct order is BADC.
