Question

Ravi buys a used watch for 2250 and spends * 250 on its repairs. If he sells
the same for 3000, find his profit per cent.​

Answer 1

GivEn:

• Ravi buy a watch (CP of watch) = ₹2250
• Spend on watch = ₹250
• He sell watch (SP of watch) = ₹3000

To finD:

• Profit percent on watch

Solution:

Here, given that Ravi buy watch for ₹2250 and spent ₹250 on reparing.

Therefore,

Total CP of watch = ₹2250 + ₹250 = ₹2500

∴ CP of watch = ₹2500

Now,

we found that CP of watch is ₹2500 and given that SP of watch is ₹3000.

$\large{\pink{\mathcal{~~~~~~~~~We\: know\: that:}}}$

• Profit = SP - CP
• Profit% = $\large{\tt{\frac{profit×100}{CP}}}$

Substituting values in formulas :

Finding Profit :

To find profit, we used formula = SP - CP

=> Profit = SP - CP

=> ₹3000-₹2500

=> ₹500

Finding profit percent :

To find profit percent, we used formula = profit ×100/CP

=> Profit % = $\large{\tt{\frac{profit×100}{CP}}}$

=> Profit% = $\large{\tt{\frac{500×100}{2500}}}$

=> Profit % = $\large{\tt{\frac{50000}{2500}}}$

=> Profit % = $\large{\tt{\cancel{\frac{50000}{2500}}}}$

=> Profit% = 20%

∴ Profit% on watch = 20%
