Let’s say that the remaining amount is x
—> \((1500000 —x)\frac{6}{100} + (\frac{2x}{3})*(\frac{4}{100}) +(\frac{ x}{3})*(\frac{3}{100}) = 76000\)

—> \(90000 —\frac{6x}{100} + \frac{8x}{300} + \frac{3x}{300} = 76000\)
\(14000 = \frac{(18x —8x —3x)}{300}\)
—> \(7x = 14000*300\)
\(x= 600000\)
—> the amount invested in fixed deposit —\(( 1500000 —600000) = 900000 \)

Answer ( C)

15L can also be written as 1500k
It can be solved easily through the following diagram

90k - 18x + 8x + 3x = 76k
on solving, x = 2k
Therefore, the amount invested in FD = 1500k - 300(2k) = 90k
Hence, C
