Question

The marks of Riju in Mathematics test increased from 20 to 30. What is the percentage of increase?

Answer 1

Step-by-step explanation:

❀$\underline{ \underline{ \text{Given}}} :$

• Initial marks of Riju = 20
• Final marks of Riju = 30

Then, Increment of the marks = 30 - 20 = 10

❀ $\underline{ \underline{ \text{To \: find}}} :$

• Percentage of increment

❀ $\underline{ \underline{ \text{Solution}}} :$

$\boxed{ \sf{Percentage \: of \: increment = \frac{Increase \: of \: marks}{Initial \: marks} \times 100\%}}$

⇒ $\sf{ \frac{10}{20} \times 100\%}$

⇒ $\boxed{ \sf{50 \: \%}}$

$\pink{ \boxed{ \boxed{ \bold{ \tt{Our \: final \: answer : \boxed{ \underline{ \tt{50\%}}}}}}}}$
