Question

An employer reduces the number of his employees in the ratio 7 : 5 and increases their wages in the ratio 15 : 28. State his bill of total wages increase in what ratio.

• A. 4 : 3
• B. 3 : 4
• C. 4 : 5
• D. 5 : 4

Answer 1

The correct option is A 4 : 3

Let the number of employees be 7x and 5x and let their wages be 15y and 28y respectively.

Then original wage bill $=7x\times 15y=Rs.105xy$

New wage bill $=5x\times 28y=Rs.140xy$
$\therefore$ The wage bill increases in the ratio $140:105=4:3$
