6. = 1200(21/20 )*15
7. after this solve yourself
8. because on C I and S I time perid maximum 5yrs

Answer 2

Answer:

P =Rs 1200

r = 5%

i = 5÷100

n = 15 years

w/k

A = P/i {(1 + i)n - 1}

A = 1200/0.05 { (1 + 0.05)¹⁵ - 1}

A = 24000 {( 1.05)¹⁵ - 1

A = 24000 ( 2.0789 - 1 )

A = 24000 × 1.0789

A = 25893.6

Therefore A = Rs 25893.6
