Answer Key-
Q-(1) Sol-(3)
Q-(3) Sol-(5)
Q-(5) Sol-(3)
We know that in a mixed double match there are two males and two females.
Two male members can be selected in 5C2=10 ways.
Having selected two male members, 2 female members can be selected in 3C2 = 3ways.
Two male and two female members can arranged in a particular game in 2 ways.
Total number of arrangements = 10×3×2 = 60 ways.
Q-(6) Sol-(3)
Ratio of efficiencies of Manish, Puneet and Ajay are 42 : 30 : 25.
Hence, the ratio of time taken by Manish and Puneet = 5 : 7
2 ratio = 10 days
1 ratio = 5 days
1050
Manish = 25 --------- 42
Puneet = 35 ---------- 30
Ajay = 42 ------------ 25
Consider, Ajay will take x days to complete the remaining work
Q-(7) Sol-(2)
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
Q-(8) Sol-(3)
Q-(9) Sol-(4)
819+67- 432= x
x = 454
Q-(10) Sol-(2)
40.70+84.32 = 125.02
