SSC CGL 6 June 2019 Shift-1

- Let's assume B's income is \( x \).

- Then, A's income will be \( 1.5x \) because A earns 50% more than B.

- Initially, their combined income is \( 1.5x + x = 2.5x \).

- A's income is increased by 40%, making it \( 1.5x \times 1.4 = 2.1x \).

- B's income is increased by 90%, making it \( x \times 1.9 = 1.9x \).

- Now, their new combined income is \( 2.1x + 1.9x = 4x \).

- The increase in combined income is \( 4x - 2.5x = 1.5x \).

- The percentage increase in their combined income is \( \frac{1.5x}{2.5x} \times 100 = 60\% \).

- The correct answer is Option 2: 60.
