If Rs. 2800 is $$\frac{2}{7}$$ percent of the value of a house, the worth of the house (in Rs.) is :

A. 800000

B. 980000

C. 1000000

D. 1200000

Answer: Option B

Solution(By Examveda Team)

Let the worth of the house be Rs. x
Then,
$$\frac{2}{7}$$% of x = 28000
$$\eqalign{ & \Rightarrow \left( {\frac{2}{7} \times \frac{1}{{100}} \times x} \right) = 2800 \cr & \Rightarrow x = \left( {\frac{{2800 \times 100 \times 7}}{2}} \right) \cr & \Rightarrow x = 980000 \cr} $$
