Question : Two numbers are in the ratio 3 : 4. The product of their HCF and LCM is 2700. The sum of the numbers is:
Option 1: 60
Option 2: 105
Option 3: 15
Option 4: 45
Correct Answer: 105
Solution : Let the numbers be 3$x$ and 4$x$ Use: HCF × LCM = Product of the numbers According to the question ⇒ HCF(3$x$, 4$x$) × LCM(3$x$,4$x$) = 2700 Now, HCF(3$x$, 4$x$) = $x$ LCM(3$x$, 4$x$) = 12$x$ So, ⇒ $x× 12x = 2700$ ⇒ $12x^{2} =

In the above-given series, add the multiples of 4 to the previous number to get the next number. 59 + 4 = 63, 63 + 8 = 71, 71 + 12 = 83, 83 + 16 = 99,
Question : If decreasing 110 by $x$% gives the same result as increasing 50 by $x$%, then $x$% of 650 is what percentage more than ($x$ + 20)% of 180? (correct to the nearest integer)
Option 1: 136%
Option 2: 90%
Option 3: 154%
Option 4: 80%
Correct Answer: 136%
Solution : According to the question, $110 \times \frac{100 - x}{100} = 50 \times \frac{100 + x}{100}$ ⇒ $11 \times (100 - x) = 5 \times (100 + x)$ ⇒ $1100 - 11x = 500 + 5x$ ⇒ $16x = 600$ ⇒ $x = \frac{600}{16}$ ⇒ $x
