Question

interests on ₹12000 for 12 years at the rate of 15% per annum is ₹180 ​

Answer 1

Step-by-step explanation:

Given P=12000 & 1 1/2 year and R = 10%

to calculate C.I for 1 year

P=Rs 1,2000 &= 1 year rate R = 10%

C.I =P (1+ r/100 ) n

= 1,2000 (1+ 10/100)

=13,200

for next 1/2 Year

P= 13,200 & n= 1/2 year and r=10%

C.I = P (1+R/2×100)2×n =13,200 (1+10/2×100)1/2×n

= 13,200 (21/20) 1

Rs ,13,860- Rs 12,000= 1860

Difference between C.I and S.I

Rs = 1,860-Rs1800= 60
