Money to be paid by Aarti
= PW of ? 440 due 1 yr hence
= {440 x 100}/{100 + (10 x 1)} = {440 x 100}/110
= 4 x 100 = ? 400
Aarti actually pays ? 220 + PW of ? 220 due yr hence
i.e. 220 + {(220 x 100) / (100 + 10 x 2)}
= 220 + (220 x 100)/120
= [220 + 183.33]
= ? 403.33
? Loss of Aarti = 403.33 - 400
= ? 3.33
.02 =(2/100) x 100% =2%
Let N / 11 = 233
Then, N = 233 x 11 = 2563
? Missing digit is 5.
121012 = 12 x 10084 + 4
? remainder = 4
We have the important relation, More work, More time (days)
? A piece of work can be done in 6 days.
? Three times of work of same type can be done in 6 x 3
= 18 days
? = 750.0003 ÷ 19.999
? ? ? 750 ÷ 20
? ? ? 375 ? 38
Subtract 20, 25, 30, 35, 40, 45 from successive numbers. So 0 is wrong.
