Question

Sita brought to watch at rupees 1600 she sold them to gain 20% on one lost 20% on other find the final gain or loss percent if the SP of both the watch is same​

Answer 1

solution

cp of first watch = 1600

percent = 20%

cp1

$\frac{100}{100 + 20} \times 1600 = 1333$

cost price of second watch =1600

loss percent = 20%

cp2=

$\frac{100}{100 - 20} \times 1600 = 2000$

Total cost price = 1333+ 2000=3333

Total loss = 1333_ 2000= 667

Loss %

$= \frac{loss}{cp} \times 100$

$loss \frac{20}{3333} \times 100 = 1.665$

Answer = 1.665%
