The banker's discount on a certain sum due 2 years hence is | 11 | of the true discount. |
10 |
The rate percent is:
Then, B.D. = Rs. | 11 | = Rs. 1.10. |
10 |
∴ Sum = Rs. | ❨ | 1.10 x 1 | ❩ | = Rs. | ❨ | 110 | ❩ | = Rs. 11. |
1.10 - 1 | 10 |
∴ S.I. on Rs. 11 for 2 years is Rs. 1.10
∴ Rate = | ❨ | 100 x 1.10 | ❩% | = 5%. |
11 x 2 |
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.
