These questions form an important category in the IBPS PO, SO, SBI and other such exams. Hence here we will see types of questions that you are most likely to see in your exam. Let us begin!

Answer 2

Concept:

Interchange of sign and numbers are that type of questions in which we have to interchange the sign or number according to requirement to get the required results.

Given:

We have given

$28 - 14 \times 3 + \frac{27}{3} = 61$

Solution:

We have to interchange the mathematical sign to get the number $61$. Interchanging the minus and plus sign,

$28 + 14 \times 3 - \frac{27}{3} \\ 28 + 42 - 9 \\ = 61$

Hence, the correct answer is

$28 + 14 \times 3 - \frac{27}{3} = 61$
