B) Rs 225700
C) Rs 228200

E) Rs 223400
Solutions:
1. B) Total no. of female employees in manager post in BOB = 7.5 × 56/100 × 100 = 420
Total work = 420 × 20 = 8400
Work done in 20 days = 420 × 5 + 400 × 5 + 380 × 5 + 360 × 5 = 7800
Therefore remaining work done by 340 females in [(8400 – 7800)/340] days = 600/340 days = 1 13/17 days
Therefore required no. of days = 20 + 1 13/17 = 21 13/17 days
2. D) Total no. of female employees in Manager post in all the banks together
= [(9.5 × 70/100) + (12.5 × 40/100) + (7.5 × 56/100) + (10.5 × 80/100) + (8.5 × 80/100)] × 100
= (6.65 + 5 + 4.2 + 8.4 + 6.8) × 100 = 3105
Therefore required average = 3105/5 = 621
3. B) Total no. of male employees in Clerk post in BOB and BOI together
= [(22.5 × 64/100) + (17 × 30/100)] × 100 = (14.4 + 5.1) × 100 = 1950 
Total no. of female employees in PO past in SBI and PNB together
= [(13.5 ×  64/100) + (15.5 × 30/100)] × 100 = (8.64 + 4.65) × 100 = 1329
Therefore required more% = [(1950 – 1329)/1329 × 100]% = 46.72% ≈ 47% more
4. C) Total number of male employees in Clerk post in BOI = 17 × 30/100 × 100 = 510
According to the question,
510 × 74 = 204 × 76 + 153 × 70 + 153 × x
=> 153x = 37740 – 15504 – 10710
=> x = 11526/153 = 75 years 4 months
5. A) The no. of female in Clerk post in BOB and BOI together
= [(22.5 × 36/100) + (17 × 70/100)] × 100 = (8.1 + 11.9) × 100 = 2000
The no. of male employees in Manager post in PNB
= 12.5 × 60/100 × 100 = 750
Therefore required ratio = 2000 : 750 = 8 : 3
6. C) Area of hall = 23*29 = 667 m2
Area of Manager room = 221 m2, of pantry= 182 m2
Area of record room = 273 m2
Area of locker room = 609 m2
Total area to be floored with marble = locker area + record keeping + pantry = 182 + 273 + 609 = 1064
So cost = 190*1064
Total area to be floored with marble = 221 + 667 = 888
So cost = 170*888
So required ratio = 170*888 : 190*1064 = 1887 : 2527
7. D) Manager room flooring cost = 170 * 221 = Rs 37570
So cost of painting = [ 2 (12*17 + 12*13) + 17*13] * 190 = Rs 178790
So required total = 178790 + 37570 = Rs 216360
8. B) Total area including all rooms = 2000 m2
Total area to be floored = 1952 = sq m
So remaining area = 2000 – 1952 = 48
So increased cost = 48*100 = Rs 5280
9. E) Area not to be renovated = 48 m2
So required % = 48/2000 * 100 = 2.4%
10. D) Cost of hall + locker area = 170 * 667 + 190*609= Rs 229100
