Question

A farmer sold two bullocks for rs 18000 each. On one bullock he gained 20% and on the other he lost 20%. Find his total gain or loss.​

Answer 1

SOLUTION -

• SP of the bullock = rs 18000
• Gain = 20 %

CP of the first bullock

= $( \dfrac{100}{100 + gain\%}) \times sp$

★ CP of the first bullock

= $( \dfrac{100}{100 + 20}) \times 18000$

$= \dfrac{100}{120} \times 18000 = rs15000$

• SP of the second bullock = rs 18000
• Loss = 20%

CP of the second bullock = $( \dfrac{100}{100 \times loss\%}) \times sp$

★ CP of the second bullock

=$( \dfrac{100}{100 - 20}) \times 18000$

$= \dfrac{100}{80} \times 18000 = rs22500$

Total cost price of the two bullocks

= rs 15000 + rs 22500 = rs 37500

Total selling price of the two bullock

= 2 × 18000 = rs 36000

Loss = CP - SP

= rs 37500 - 36000 = rs 1500

hence , the farmer suffers the loss of rs 1500.
