Question 81

If 9/4th of 7/2 of a number is 126, then 7/2th of that number is ..............

Solution

Let the number be $$x$$

According to ques,

=> $$\frac{9}{4} \times \frac{7}{2} \times x = 126$$

=> $$\frac{63}{8} x = 126$$

=> $$x = \frac{126}{63} \times 8$$

=> $$x = 2 \times 8 = 16$$

$$\therefore (\frac{7}{2})^{th}$$ of the number = $$\frac{7}{2} \times 16$$

= $$7 \times 8 = 56$$

=> Ans - (A)
