Answers with 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.
6. c; Take the Weighted average.
Total number of boys=611
Total number of girls=145
So, Ratio of boys to girls= 611:145= 4.21:1≈4:1
