Answer»

Rs. 5000



Let X, y and z be the amount invested in schemes A, B and C respectively. Then,

(x * 10 * 1)/100 + (y * 12 * 1)/100 + (z * 15 * 1)/100 = 3200

10x + 12y + 15z = 320000

Now, z = 240% of y = 12/5 y

And, z = 150% of x = 3/2 x

x = 2/3 z = ( 2/3 * 12/5) y = 8/5 y

16y+ 12y + 36Y = 320000

y = 5000

Sum invested in scheme B = Rs. 5000.
