1. 5 : 7
2. 7 : 5
3. 5 : 4
4. 7 : 4

Answer 1

Correct Answer - Option 4 : 7 : 4

Given:

A got double the profit than B in a business. A and B invested Rs. 3200 and 2800 respectively.

Formula:

Ratio of Profit = ratios of product of Amount invested and time

Calculation:

Let B got x as profit then A got 2x

2x/x = 3200 × t₁/2800 × t₂

2/1 = 8t₁/7t₂

t₁/t₂ = 7/4
