d) 8%​

Answer 1

Answer :-

• Option (B) Value of x = 6.

Explanation :-

Here, we are given with an expression and we have to find the value of x.

Let's Solve.

➙ x% of 250 = 15.

➙ x/100 × 250 = 15.

➙ 250x/100 = 15.

➙ 25x/10 = 15.

➙ 25x = 15 × 10.

➙ 25x = 150.

➙ x = 150 ÷ 25.

➙ x = 6.

Therefore, Value of x = 6.

Verification :-

➙ x% of 250 = 15.

➙ 6/100 × 250 = 15.

➙ 25 × 6/10 = 15.

➙ 150/10 = 15.

➙ 15 = 15.

LHS = RHS.

Hence, Verified.
