CI = 14800{ [ 1 + 13.5/100]2 – 1 }
= 14800 { [1 + 27/200]2 – 1
= 14800 { 2 + 27/200}{27/200}
= (74)[2 + 27/200](27) =
1998[2 + 27/200] = 3996 + 269.73 = Rs. 4266

Work done by P in 1 day = 1/18
Work done by Q in 1 day = 1/15
Work done by Q in 10 days = 10/15 = 2/3
Remaining work = 1 – 2/3 = 1/3
Number of days in which P can finish the remaining work = (1/3) / (1/18) = 6

Let Mohan’s salary be Rs.100.
When increased by 20%, Mohan’s salary = Rs.120
Again when decreased by 20%, Mohan’s salary = 120 – 24 = Rs. 96.
But present salary is Rs. 7200
for, 96 —> 100 ; 7200 —> ?
Required salary is 7200/96 * 100 = Rs. 7500
