Question

14. A tricycle is sold at a gain of 15%. Had it been sold for 108 more, the profit would have
been 20%. Find its cost price. ​

Answer 1

Answer:

• If there is Same Terms (Profit, Profit) or (Loss, Loss). Then we Subtract the Percentage.
• If there is Opposite Terms (Profit, Loss) or (Loss, Profit). Then we Add the Percentage.

$\underline{\bigstar\:\:\textsf{According to the Question :}}$

$:\implies\tt CP \times (Profit-Profit)\%=More/Less\\\\\\:\implies\tt CP \times (20 - 15)\% = 108\\\\\\:\implies\tt CP \times 5\% = 108\\\\\\:\implies\tt CP \times \dfrac{5}{100} = 108\\\\\\:\implies\tt CP \times \dfrac{1}{20} = 108\\\\\\:\implies\tt CP = 108 \times 20\\\\\\:\implies\underline{\boxed{\textsf{\textbf{CP = Rs. 2,160}}}}$

⠀

$\therefore\:\underline{\textsf{Cost Price of tricycle is \textbf{Rs. 2,160}}}.$
