1000+ Bunna Bank Exam Questions and Answers Pdf - 1

Ans: A

1 man = 3 boys

[Given]: Wages for five days = Rs. 800

∴ Wages for one day = $${800} / {5}$$ = Rs. 160.

The wages of Rs. 160 are to be divided among the man and boy in the ratio 1 : 3.

∴ Wages of the boy per day = $${1}/{4} × 160$$ = Rs. 40.

Ans: D

Part of the work done by 8 men in 6 days = $${6}/{12}$$ = $${1}/{2}$$

Remaining work = $$1 - {1}/{2}$$ = $${1}/{2}$$

Required number of days = $${1}/{2} × 8$$ = 4 days.

Ans: D

Part of work done by B and C in 3 days = 3$$({1/9} + {1/12)$$ = $${7}/{12}$$

Remaining work = $$1 - {7}/{12}$$ = $${5}/{12}$$

Remaining work is done by A in $${5}/{12} × 24$$ = 10 days.

Ans: C

Males : Females : Children

6 × 12:8 × 18:18 × 10

72 : 144 : 180

2 : 4 : 5

So, 2 males = 4 females = 5 children

4 males + 12 females + 20 children

= 4 + 6 + 8 = 18 males.

∴ 6 males finished a piece of work in 12 days.

∴ 18 males finished the work = $${12 × 6} / {18}$$ = 4 days.

Work in 2 days = $${2}/ {4}$$ = $${1}/{2}$$

Rest of the work will be finished in a day by = 18 × 2 = 36 males.

Ans: D

Time taken by Ramesh = $$4 × {2}/{3}$$ = $${8}/{3}$$ days

Work done by all the three in 1 day

= $${1}/{4} + {1}/{6} + {3}/{8}$$

= $${6 + 4 + 9} / {24}$$ = $${19}/{24}$$

∴ Required time = $${24}/{19}$$ = $$1{5}/{19}$$ days.
