Question 138

The total discount on Rs. 1860 due after a certain time at 5% is Rs. 60. find the time after which it is due:

Solution

Given,

Total discount = Rs 60

Amount = Rs 1860

Rate = 5%

Let Time = T

Total discount = $$\frac{A\times R\times T}{100+RT}$$

$$=$$> $$60=\frac{1860\times5\times T}{100+5T}$$

$$=$$> 100 + 5T = 155T

$$=$$> 150T = 100

$$=$$> T = $$\frac{2}{3}$$ year

$$=$$> T = $$\frac{2}{3}$$ x 12 months = 8 months

Hence, the correct answer is Option C
