Answer 1

HELLO!!

ANSWER:

Half yearly compound interest = ₹2648

EXPLANATION:

GIVEN:

Principal (P) = ₹8000
Rate of interest (r) = 10%
Time (n) = 18 months = 18/12 years = 3/2 years

TO FIND:

Half yearly compound interest

SOLUTION:

Amount (A) = P[1 + ½(r/100)]power 2n

A = 8000[1 + ½(10/100)]power2*3/2

A = 8000[1 + 1/10)]³

A = 8000[10/10 + 1/10)]³

A = 8000[11/10]³

A = 8000[1.1]³

A = 8000[1.331]

A = ₹ 10648

Compound interest (CI) = A - P

CI = 10648 - 8000

CI = ₹2648

HOPE IT HELPS YOU!!
