Question

Cost of a toffee is $50$ Paise and the cost of a chocolate is $₹10$, What will be the ratio of the cost of a toffee to the cost of a chocolate?

• A. $1:5$
• B. $5:1$
• C. $1:20$
• D. $20:1$

Answer 1

The correct option is C

$1:20$

Given that,

Cost of a toffee $=$$50paise$

Cost of a chocolate $=$$₹10$

Convert the given unit into same unit.

We know that,

$₹1=100paise$

Therefore, $₹10=100\times 10paise=1000paise$

ratio of the cost of a toffee to the cost of a chocolate$=\frac{50paise}{1000paise}=\frac{1}{20}$ ( Divide both numerator and denominator by their HCF $50$)

Hence, the ratio of the cost of a toffee to the cost of a chocolate is $1:20$
