Explanatory Answer

Method of solving this CAT DILR Question from Analytical Reasoning question

(b) Under new scheme salary for 9th and 11th week = 2 (25 × 6 – 5 × 4 ) × 6 = Rs 1560

Now salary for 10th and 12th week = 2( 25 × 4 – 5 × 6 ) × 6 = Rs 840

Total salary for 3rd month = 1560 + 840 = Rs 2400

Under previous scheme total salary for 3rd month = Rs 1920

Difference = 2400 – 1920 = Rs 480
