Question

Find the rate when principal = ₹ 5200, SI = ₹ 975 and time = 2 ½ years.

Answer 1

Given: – P = ₹ 5200, SI = ₹ 975, t = 2 ½ years = 5/2

We know that,

R = (100 × SI) / (P × T)

= (100 × 975)/ (5200 × (5/2))

= (100 × 975 × 2) / (5200 × 5)

= (1 × 975 × 2) / (52× 5)

= (195 × 1) / (26× 1)

= (195/26)

= 7.5

= 7 ½ % p.a.
