• D. Rs.1800, Rs.2200 and Rs.3000

Hint:

Add ratio parts first, then divide the total to get the unit value.

Answer 1

The Correct Option is B

Concept: Distribute total amount according to ratio parts. Explanation: Ratio = 3 : 4 : 5 Total parts = $3 + 4 + 5 = 12$ Value of one part: \[ 7200 \div 12 = 600 \] A’s salary: \[ 3 \times 600 = 1800 \] B’s salary: \[ 4 \times 600 = 2400 \] C’s salary: \[ 5 \times 600 = 3000 \]
