Question

on selling 17 balls for Rs 720, there is a loss equal to the cost price of 5 balls. The cost price of the ball is?



​

Answer 1

Answer:

508.25

Step-by-step explanation:

I Want To Say You That here one mistake c. p. of ball not equal to 5 balls of price but s. p. of ball is equal to rupees of 5 balls.

S.p. of 17 balls =720

s. p. of one ball =720/17

=42.35

so, loss =s. p. of 5 balls

loss =42.35 x5

= 211.75

Then, the c. p. =s. p. -loss

=720-211.75

=508.25

Answer 2

$\large{ \underline {\sf☆Given:-}}$

• Selling price of 17 balls = 720
• Loss equal to the price of 5 balls

$\large{ \underline {\sf☆Let:-}} </p><p>$

• The cost price of a ball be Rs. x.

So ,

• The cp of 17 balls = 17x
• The cp of 5 balls = 5x

$\large{ \underline {\sf☆Solution:-}}$

$\sf \mapsto Loss = Cp-Sp$

$\sf \mapsto5x = 17x - 720$

$\sf \mapsto720 = 17x - 5x$

$\sf \mapsto720 = 12x$

$\sf \mapsto x = \large \frac{720}{12}$

$\sf \mapsto x = 60$

$\star{ \underline{ \boxed{ \sf \pink{The \: cost \: price \: of \: 1 \: ball = 60 rs}}}}$
