Answer» Correct Answer - Option 3 : 10 : 7 Given: 42% of first number is equal to the 60% of second number. Calculation: Let the first number be x. Let the second number be y. According to the question; ⇒ \(\frac{{42}}{{100}} \times x\) = \(\frac{{60}}{{100}} \times y\) ⇒ \(\frac{x}{y}\;\) = \(\frac{60}{42}\;\) ⇒ \(\frac{x}{y}\;\)= \(\frac{10}{7}\;\) The ratio of first number to the second number is 10 : 7. |
