Option 1: $\frac{4}{15}$

Option 2: $\frac{8}{15}$

Option 3: $\frac{11}{15}$

Option 4: $\frac{11}{30}$

Team Careers360 13th Jan, 2024

Correct Answer: $\frac{4}{15}$


Solution : One day work of Tina = $\frac{1}{15}$
One day work of Manya = $\frac{1}{18}$
One day work of Tina and Manya = $\frac{1}{15}+\frac{1}{18}$ = $\frac{6+5}{90}$ = $\frac{11}{90}$
Six day work of Tina and Manya = $\frac{11}{90}\times6$ = $\frac{11}{15}$
Remaining work = $(1-\frac{11}{15})$ = $\frac{4}{15}$

Question : A dealer marks his goods at 44% above the cost price. Then he allows 50% discount on it. What would be his loss percentage?

Option 1: 25%

Option 2: 28%

Option 3: 26%

Option 4: 32%

Team Careers360 15th Jan, 2024

Correct Answer: 28%


Solution : Let the cost price be 100.
Marked price above 44% = 144
Discount = 50%
Selling price = $\frac{\text{Discount}}{100}\times$ Marked price
= $\frac{50}{100}\times144$
= 72
Loss = cost price – selling price
= 100 – 72
= 28
Loss percent = $\frac{\text{Loss}}{\text{Cost price}}\times100$%
= $\frac{28}{100}\times100$%
