Question 67

If 2145 : x :: 3003 : 42, then the value of y so that x : 2508 :: y : 11704, is:

Solution

Given, 2145 : x :: 3003 : 42

$$=$$> $$\frac{2145}{x}=\frac{3003}{42}$$

$$=$$> $$x=\frac{2145\times42}{3003}$$

$$=$$> $$x=30$$

x : 2508 :: y : 11704

$$=$$> $$\frac{x}{2508}=\frac{y}{11704}$$

$$=$$> $$\frac{30}{2508}=\frac{y}{11704}$$

$$=$$> $$y=\frac{30\times11704}{2508}$$

$$=$$> $$y=140$$

Hence, the correct answer is Option D
