Question

Direct compound variation if mohan works 5 hours each day for 4 days he earns rs 1400. How much can he earn if he works for 6 days and8 hours each day

Answer 1

See,

It's given that Mohan works for 5 hours a day.

So, therefore 4 days= 4

$4 \times 5 \: which \: is \: 20$

Similarly,

if he works for 6 hours a day.

So hence

$6 \times 8 \: which \: is \: equal \: to \: 48$

By direct variation,

20=144

48=?

$48 \times 1400 \div 20 \: which \: is \: 3360$

He will earn rupees 3360/-
