Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. 716.

Let the number = x

(200/3)% of 75% of 1/8 of the number is 179:

⇒ (2/3) × (75/100) × (1/8) × x = 179

⇒ (2/3) × (3/4) × (1/8) × x = 179

⇒ x = 179 × 16

(100/3)% of 3/4 of that number is:

⇒ 100/300 × 3/4 × 179 × 16

⇒ 1/3 × 3/4 × 179 × 16

⇒ 1/3 × 3 × 179 × 4

⇒ 179 × 4 = 716
