Question : The difference of $5.\overline{76}$ and $2.\overline{3}$ is:
Option 1: $2.\overline{54}$
Option 2: $3.\overline{73}$
Option 3: $3.\overline{46}$
Option 4: $3.\overline{43}$
Correct Answer: $3.\overline{43}$
Solution : $5.\overline{76} = 5 + \frac{76}{99}$ $2.\overline{3} = 2 + \frac{3}{9}$ Now, $5 + \frac{76}{99} - 2 - \frac{3}{9}$ = $3 + (\frac{76}{99} - \frac{3}{9})$ = $3 + (\frac{43}{99})$ = $3\frac{43}{99}$ = $3.\overline{43}$ Hence, the correct answer is $3.\overline{43}$.
Question : The least common multiple of a and b is 42. The LCM of 5a and 11b is:

Option 2: 4620
Option 3: 210
Option 4: 462
Correct Answer: 2310
Solution : The least common multiple of a and b is 42 According to the question, LCM(a, b) = 42 LCM(5a, 11b) = LCM of {LCM(5,11)(a,b)} LCM(55, 42) = 55 × 42 = 2310 Hence, the correct answer is 2310.
Question : A man invests half his capital at the rate of 10% per annum, one-third at 9% and the rest at 12% per annum. The average rate of interest per annum, which he gets, is:
Option 1: 9%
