Why this answer is correct

Given Data:

 

Difference between CI and SI: Rs. 122

 

Rate of Interest: 5% per annum

 

Time Period: 2 years

 

Concept/Formula Used:

 

The formula for the difference between CI and SI for 2 years is given by: Difference = (P × (R/100)^2), where P represents the principal sum, and R represents the rate of interest.

 

Solution:

 

Re-arrange the formula to isolate the principal sum 'P':

 

⇒ P = Difference ÷ (R/100)^2

 

Substitute the given values: ⇒ P = Rs. 122 ÷ (5/100)^2

 

⇒ P = Rs. 122 ÷ 0.0025 ⇒ P = Rs. 48800

 

Hence, the correct answer is  Rs. 48800.

View answer & explanation

Correct answer

Answer: (a)A.

24

Why this answer is correct

Given Data:

 

The number to which we want to add is 2055.

 

The number by which the sum has to be divisible is 27.

 

Concept/Formula Used:

 

When we want to find the smallest number to add to a given number so it's divisible by another number, we can use the remainder theorem.

 

Solution:

 

Divide the given number by 27 and obtain the remainder:

 

⇒ 2055 ÷ 27 = 76 remainder 3

 

Since we want the number to be exactly divisible by 27, we subtract the remainder from 27 to find out how far we are from the next multiple of 27:  ⇒ 27 - 3 = 24

 

Therefore,the correct answer is  24.
