Question

15 men, 18 women and 12 boys working together earned Rs 2070 If the daily wages of a man, a woman and a boy are in the ratio 4 : 3 : 2 the daily wages ( in Rs) of 1 man, 2 women and 3 boys are

• A. 135
• B. 180
• C. 240
• D. 205

Answer 1

The correct option is C 240

Suppose the daily wages of a man, a woman and a boy are 4k, 3k and 2k respectively.

$\therefore$ $15\times 4k+18\times 3k+12\times 2k=2070$

$\Rightarrow 60k+54k+24k=2070\Rightarrow 138k=2070\Rightarrow k=15$

$\therefore$ Daily wages of a man, a woman and a boy are $Rs60,Rs45$ and $Rs30$respectively,

$\therefore$Daily wages of 1 man + 2 women + 3 boys $=Rs60+2\times Rs45+3\times Rs30=Rs60+Rs90+Rs90=Rs240$
