In the following number series, a wrong number is given. Find out that wrong number.
16, 19, 21, 30, 46, 71, 107
In the following number series, a wrong number is given. Find out that wrong number.
7.5, 47.5, 87.5, 157.5, 247.5, 357.5, 487.5
The given number series is based on the following pattern :
487.5  357.5 = 130
357.5  247.5 = 110
247.5  157.5 = 90
157.5  87.5 = 70
87.5  47.5 = 40
87.5  37.5 = 50
37.5  7.5 = 30
Clearly, 47.5 is the wrong number. It should be replaced by 37.5.

A person invests Rs. 12,000 as fixed deposit at a bank at the rate of 10% per annum simple interest. But due to some pressing needs he has to withdraw the entire money after 3 years, for which the bank allowed him a lower rate of interest. If he gets Rs. 3320 less than what he would have got at the end of 5 years, the rate of interest allowed by the bank is:
Principal = Rs. 12000Rate % = 10%Interest would have been received by person in 5 years Interest received by the person after 3 years = Rs(6000 – 3320) = Rs 2680.By using formula,Rate %
On a certain sum of money, the difference between the compound interest for a year, payable halfyearly, and the simple interest for a year is Rs. 180. If the rate of interest in both the cases is 10%, then the sum is:
Nikita bought 30 kg of wheat at the rate of Rs. 9.50 per kg and 40 kg of wheat at the rate of Rs.8.50 per kg and mixed them. She sold the mixture at the rate of Rs. 8.90 per kg. Her total profit or loss in the transaction was
C.P of wheat = 30 × 9.5 + 40 × 8.5
= 285 + 340 = Rs. 625
SP of wheat = 70 × 8.9 = Rs. 623
Loss = CP – SP = 625 – 623 = Rs. 2 Loss
