Answer & Explanation

1. 4; The constant present in the first week combination is either similar or different from the constant present in the second week combination. Hence we can’t find the expenditures of first and second weeks.

Hence data inadequate.

2. 1; Three tablets/day would mean the hypertensive has to be taken 90 times in 30 days.

The increase is of Rs 2.50 for 10 tablets

Hence increase will be of 2.50 × 9 = 22.50 for 90 tablets

Asthmatic has to consume 30 tablets.

∴ increase = 5.00 × 3 = 15.00

∴ total increase = 22.50 + 15 = 37.50.
