Question

PETER SELLS TWO WATCHES FOR Rs.198 EACH GAINING 25% ON ONE AND LOOSING 20% ON THE OTHER FIND HIS GAIN OR LOSS PERCENT ON THE WHOLE. ​

Answer 1

Answer:

88.8091%

Step-by-step explanation:

$let \: watch \: 1 \: be \: x. \\ \frac{125}{100} \times y = 198 \\ \\ y = 198 \times \frac{100}{125} \\ \\ y = 198 \times \frac{4}{5} \\ \\ y = 158.4$

$\mathfrak \red{Price\:of\: watch \:1\: is\: 158.4₹.}$

$let \: watch \: be \: z. \\ \frac{80}{100} \times y = 198 \\ \\ y = 198 \times \frac{100}{80} \\ \\ y = 198 \times \frac{5}{4} = 247.5$

$\mathfrak \red{Price\:of\: watch \:1\: is\: 247.5₹.}$

$(158.4 + 247.5) = cp \\ 2(198) = sp \\ cp = 445.9 \\ sp = 396 \\ \frac{396}{445.9 } = \frac{396 \times 10}{445.9 \times 10} \\ \\ \frac{3960}{4459} \times 100 = loss\% \\ \\ \frac{3960}{4459} \times 100 = 88.8091\%$
