Here, P = ? 2668, T = 5 yr, A = ? 4669
We know that,
Amount (A) = Principal (P) + (Simple Interest) SI
4669 = 2668 + SI
? SI = 4669 - 2668 = ? 2001
Again, SI = (P x R x T)/100
? 2001 = (2668 x R x 5)/100
? R= (2001 x 100) / (2668 x 5)
= (2001 x 5)/667
= 15%
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.
