$\underline\mathbf{solution}$

▪️Amount = Rs. 5850

▪️Time (T) = 6 years

▪️Rate (R) = 5% p.a.

▪️Sum = Principal (P)

▪️Let the Principal be Rs. x

▪️A/Q.

▪️Amount = Principal + S.I.

▪️5850 = x + (PRT / 100)

▪️⇒ 5850 = x + (x × 5 × 6 / 100)

▪️⇒ 5850 = x + (30x / 100)

▪️⇒ 5850 = x + (3x / 10)

▪️⇒ 5850 = (10x + 3x) / 10

▪️⇒ 5850 = 13x / 10

▪️⇒ 5850 × 10 / 13 = x

▪️⇒ 450 × 10 = x

▪️⇒ 4500 = x

▪️Hence, the sum is 4500.
