Let the amount at 6% be x
Amount at 10% be (10000 ?x)
At 9.2 % interest, SI = 10000 X 9.2 X 1/100 = 920
Amount = 10920
? 6x/100 + (10000 ? x)10/100 = 920
? 6x ? 10x + 100000 = 92000
? 4x = 8000
? x = 2000
Money lent at 10 % = 10000 ? 2000 = 8000
47/10000 = .0047
.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.
