A box contains 280 coins of one rupee, 50 paise and 25 paise. The value of each kind of the coins are in the ratio of 8 : 4 : 3. Then the number of 50 paise coins is = ?

Answer:- 1

Explanation:-

Solution:

	Rs. 1	:	50 P	:	25 p
Values of coins	8x	:	11x	:	3x
Number of coins	8x_×1	:	4x_×2	:	3x_×4
	8x	:	8x	:	12x

\begin{aligned} ∴ Total coins \\ \Rightarrow 8 x + 8 x + 12 x = 28 x \\ \Rightarrow 28 x = 280 (given) \\ \Rightarrow x = \frac{280}{28} \\ \Rightarrow x = 10 \end{aligned}

$\eqalign{ & \therefore {\text{Total coins}} \cr & \Rightarrow 8x + 8x + 12x = 28x \cr & \Rightarrow 28x = 280{\text{ (given)}} \cr & \Rightarrow x = \frac{{280}}{{28}} \cr & \Rightarrow x = 10 \cr}$ ∴ Number of 50 P coins are 8x
= 8 × 10 = 80
