Answer 1

The weight of ravi is 80 kg.

Step-by-step explanation:

Let the weight of ravi is x kg.

Given:

• Akash weight is 70 kg.
• Ravi weight is 40 kg less than twice of 3/4 of his original weight.

$= > x = 2 \times \frac{3}{4} \times \: x - 40 \\ = > x = \frac{3x}{2} - 40 \\ = > \frac{3x}{2} - x = 40 \\ = > \frac{3x - 2x}{2} = 40 \\ = > \frac{x}{2} = 40 \\ = > x = 80 \: kg$

The weight of ravi is 80 kg.

Answer 2

Weight of Ravi will be 80kgs

Weight of Akash = 70kg  (Given)

Let weight of Ravi be = x kgs

Since, weight of Ravi is 40kgs less than twice of 3/4 of his original weight, then -  

x = 2 × 3/4 × x - 40

x = 3x/2 - 40

3x/2 - x = 40

3x-2x/2 = 40

x/2 = 40

x = 40 × 2

x = 80

Therefore, weight of Ravi is 80kg.
