Answer: Option D
Solution(By Examveda Team)
The total wages earned during the 15 days that the worker worked , = 15 × 90= Rs. 1350 The total wages earned during the first 7 days
= 7 × 87
= Rs. 609 The total wages earned during the last 7 days
= 7 × 92
= Rs. 644 Total wages earned during the 15 days, = wages during first 7 days + wage on 8th day + wages during the last 7 days. 1350 = 609 + wage on 8th day + 644 wage on 8th day = 1350 - 609 - 644 = Rs. 97
