1). PQR = 12). P2 = QR3). Q2 = PR4). R = P2Q

Answer»

Let the rate be R and time be t in both cases.

As given, Q is the SI on P, we can write,

⇒ Q = P ? r ? t/100----- (1)

Also given that, R is SI on Q, we can write,

⇒ R = Q ? r ? t/100----- (2)

Dividing equation (2) by equation (1), we get,

⇒ Q/R = P/Q

∴ Q2 = PR
