Answer 2

Given :

• No of books Saumya had = 50
• 10% of her books got spoilt
• her book collection increased by 40%

To find :

• many books does Saumya have now

Solution :

⇒ Let's see how many books were spoilt due to rain.

Spoilt Books = 50/100 x 10

                     = 50 x 10/100

                     = 500/100

                     = 5

⇒ Now, we have find out how many books are left with her.

Books left = 50 - 5

                 = 45

⇒ It is said that 40% of her collection is increased. So, let's find out how many.

Increased = 45 + 40%

→ 45 + 40%

→ 45 × 40/100 + 45

→ 45 × 0.4 + 45

→ 18 + 45

→ 63

               

Therefore, Saumya has 63 books now.
