Question

Christopher borrowed 1.5 lakh from a
bank at 17% p.a. simple interest. What
amount must he pay back after 3 1/2 years?​
​if the answer is ₹2,39,250., what are the steps.​

Answer 1

Answer:

89250

Step-by-step explanation:

p = 1.5 lakh

r = 17

t = 3 1/2 = 7/2 = 3.5

si = prt/100

 = 150000 x 17 x 3.5/100

 = 35 x 17 x 150

 =89250

Answer 2

Step-by-step explanation:

Money Borrowed= Principal

Principal= 1.5 lakh

Interest rate= 17%

Time = 3 $\frac{1}{2}$

Interest= $\frac{PrincipalX RateX Time}{100}$

So,

Interest= $\frac{150000X17X3.5}{100}$   (converted fraction of time in decimals)

Interest= $\frac{150000X17X35}{100X10}$   (removing point)

Interest= $\frac{8,92,50,000}{1000}$

Interest= 89,250

Amount to be paid=Principal + Interest

                              = 150000+89250

                              =2,39,250
