? = 38.5 - A can do a piece of work in 8 days which B can destroy in 3 days. A has worked for 6 days, during the last 2 days of which B has been destroying. How many days must A now work alone to complete the work?
6(1/9) Days4(1/8) Days3(1/2) Days7(1/3) Days5(1/6) DaysOption D
In 6 days part of the work done by A = 6/8 = ¾
During 2 days, part of the work destroyed by B = 2/3
Work done = 3/4 – 2/3 = 1/12
Remaining work = 1 – 1/12 = 11/12
Required no of days = 11/12 × 8 = 7(1/3) Days - A trader sells two bullocks for Rs. 8,400 each, neither losing nor gaining in total. If he sold one of the bullocks at a gain of 20%, the other is sold at a loss of:
16(1/5)%12(3/8)%8(1/6)%14(2/7)%10(1/9)%Option D
S.P. of two bullock = 8400 + 8400 = Rs. 16800
CP of first bullock = = 7000
CP of second bullock =16800 – 7000
Required % loss = [9800-8400]/9800*100 = 14(2/7)% - Difference between female employees of HR dept. in all companies together (excluding company S) and the female employees of Marketing dept. in all companies together (excluding company Q)?
