A man invests rs6750,partly in shares of 6% at rs140 and partly in shares of 5% at rs 125.if his total income is rs280,how much has he invested in each?

Answer 1

shares bought at RS140 --- x
shares bought at RS125 --- y

amount invested at 6% --- 140x
amount invested at 5% --- 125y

140x + 125y = 6750 **

.06(140x) + .05(125y) = 280
8.4x + 6.25y = 280
times 20
168x + 125y = 5600 ***

subtract ** from ***
28x = -1150

not possible.
Unless you can find an error in my calculations, this question is bogus
