Let we take Ritam as "a" and

Let we take Sohan as "b" .

Ratio of time

=> a : b

=> 2 : 3

$( \frac{a}{b} = \frac{150\%}{100\%} = \frac{3}{2} )$

efficiency of work = 2 : 3 (Efficiency is always is always proportion to time ).

Total work = 18 days × ( 2 + 3 ) unit.

= 90 units .

a completes work in

$= \frac{90units}{3 \: units \: per \: day \: } \\ \\ = \: 30 \: days \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:$

So the Ritam will take 30 days to do the work .
