Answer:Rate of interest is 16 % p.a.For Amar,Principal (P) = Rs 2250Time (T) = 7/2 yearsRate (R) = r % p.a.We know, Simple Interest (S.I.) = (P × R × T) ÷ 100∴ SI₁ = Rs (2250 × r ×7/2) ÷ 100 = Rs 78.75 rFor Chaman,Principal (P) = Rs 2500Time (T) = 7/2 yearsRate (R) = r % p.a.We know, Simple Interest (S.I.) = (P × R × T) ÷ 100∴ SI₂ = Rs (2500 × r × 7/2) ÷ 100 = Rs 87.5 rGiven, Chaman paid Rs 140 more interest than Anand.So, SI₂ – SI₁ = Rs 140⇒ Rs (87.5 r – 78.75 r) = Rs 140⇒ 8.75 r = 140⇒ r = 140/8.75= 16%Rate = 16% p.a.
