Number 9 is B, and number 10 is D
2 : 3 (reduced by a factor of 7 from 14 : 21) and 56 : 84 (increased by a factor of 4)
Let the numbers be 2x and 3x.
<u>According to the Question</u>,
⇒ 2x + 3x = 45
⇒ 5x = 45
⇒ x = 45/5
⇒ x = 9
<u>Now finding the values of both the number,</u>
⇒ 2x = 2 × 9
= 18
⇒ 3x = 3 × 9
= 27
<u>Hence, the value of both the number is 18 and 27 respectively.</u>
