Step-by-step explanation:
Let one part = Rs. x
∴ Second part = Rs. (15,600 –x)
By the given condition
= (x × 5 × 5)/100 = ((15,600 – x) × (9/2) × 6)/100
⇒ 25x = 27 × 15,600 – 27x
⇒ 25x +27x = 27 × 15,600
⇒ 52x = 27 × 15,600
⇒ x = (27 × 15,600)/52 = 27 × 300 = 8100
Hence one part = Rs. 8100 and second part
Rs. (15,600 – 8,100) = Rs. 7500
