Question : The sides of a triangular field are 62 m, 186 m, and 279 m. Find the greatest length of tape that would be able to exactly measure each of them without any fractions.
Option 1: 62 m
Option 2: 93 m
Option 3: 31 m

Question : A and B can do a piece of work in 15 days. B and C can do the same work in 10 days and A and C can do the same in 12 days. The time taken by A, B and C together to do the job is:
Option 1: 4 days
Option 2: 9 days

Question : A shopkeeper allows a 20% discount on the marked price of an article and he suffers a loss of 12%. If the article is sold at marked price, then what will be the profit percentage?
Option 1: 10%
Option 2: 12.5%
Option 3: 9.69%
Option 4: 8.33%
Correct Answer: 10%
Solution : Given, Discount = 20% Loss = 12% We know, $\frac{\text{Marked price}}{\text{Cost Price}}=\frac{100\pm\text{Profit/Loss}}{100-\text{Discount}}$ ⇒ $\frac{MP}{CP}=\frac{100-12}{100-20}$ ⇒ $\frac{MP}{CP}=\frac{88}{80}$ ⇒ $\frac{MP}{CP}=\frac{11}{10}$ If there is no discount, means discount = 0%, then profit% ⇒ $\frac{MP}{CP}=\frac{100+\text{profit}}{100-\text{discount}}$ ⇒ $\frac{11}{10}=\frac{100+\text{profit}}{100}$ ⇒ $110=100+\ \text{profit}$ ⇒ Profit % = 10% Hence, the correct answer
Question : Two numbers are in the ratio 12 : 7. If their HCF is 25, find the numbers.
