Answer» Correct Answer - Option 3 : 7.1

Given

2562.5 × 164.5 ÷ 44.8 = 16x

Formula Used

am × an = am + n, (am)n = am × n, am÷ an = am - n

Calculation

2562.5 × 164.5 ÷ 44.8 = 16x

⇒ (162)2.5 × 164.5 ÷ 42× 2.4 = 16x

⇒ 162 × 2.5 × 164.5 ÷ 162.4 = 16x

⇒ 165 × 164.5 ÷ 162.4 = 16x

⇒ 165 + 4.5 - 2.4 = 16x

⇒ 169.5 - 2.4 = 16x

⇒ x = 9.5 – 2.4 = 7.1

The value of x is 7.1.
