Solution

Money invested = Rs 35,000 

For 'Lak me' shares: 

Market value = Rs 40 

Amount invested = Rs 6,000 

Income from investment = `6/40 xx 6000` = Rs 900

For 'Volta' shares: 

Market Value = Rs 125 

Amount invested = Rs 15,000 

Income from investment = `8/125 xx "Rs" 15000` = Rs 960

For 'BPL' shares: 

Market value = Rs x 

Amount invested = Rs (35,000-6,000-15,000) = Rs 14,000 

Income from investment = Rs `12/x xx 14000` = Rs `168000/x`

Total investment from shares = Rs 900 + Rs 960+Rs `168000/x`

Pramod wants  `8 1/7 %` return on his investment = `57/7 %`

`57/(100 xx 7) xx  "Rs"  35000` = Rs 2850

Therefore, Rs 2,850 - Rs 900 + Rs 960 + Rs `168000/x`

Rs 990 x - Rs 1,68, 000 x = Rs 169.69 = Rs 170 

Hence, Pramod bought BPL shares at Rs 170 per share.
