Question . 330
If Bankatlal is paid Rs. 20 per working hour in the 1st week, what is his salary for the 1st month?
Explanatory Answer
Method of solving this CAT DILR Question from Analytical Reasoning question
(a) Salary in the first week = Rs 20 per working hour As the working pattern changes next week, so wage/hr
for the 2nd and fourth week = 20/2 = 10
Work and Rest hrs/day for the 2nd and 4th weeks respectively are 2 and 5 hrs.
A week consist of 6 days and a month of 4 week
Salary from 1st and 3rd week = 20 × 5 × 2 × 6 = Rs 1200
Salary for 2nd and 4th week = 2 × 10 × 6 × 2 = Rs 240
Salary for 1st month = 1200 + 240 = Rs 1440
