Question

Sujata had some toffees. After distributing 60%of them if 20 toffees are still with her, how many did she give away.

Answer 1

Given that:

• Sujata had some toffees.
• After distributing 60% of them.
• 20 toffees are still with her.

To Find:

• How many did she give away.

Let us assume:

• Total number of toffees be x.

According to the question.

↠ x = 60% of x + 20

↠ x = 0.6x + 20

↠ x - 0.6x = 20

↠ 0.4x = 20

↠ x = 20/0.4

↠ x = 50

Number of toffees distributed,

= Total toffees - toffees left

= 50 - 20

= 30

Hence,

• She gave away 30 toffees.

Answer:

Question :-

Given :-

• Sujata had some toffees. After distributing 60%of them if 20 toffees are still with her.

Find Out :-

• How many did she give away.

Solution :-

Let, the total toffees is a

According to the question or ATQ : -

➙ a = 60% × (a + 20)

➙ a = $\sf \dfrac{60}{100}$ × (a + 20)

➙ a = 0.6 × (a + 20)

➙ a = 0.6a + 20

➙ a - 0.6a = 20

➙ 0.4a = 20

➙ a = $\sf \dfrac{20}{0.4}$

➙ $\small\bold\green{a =\: 50}$

Hence, number of toffees she give away :

➨ Number of toffees = 50 - 20

➨ ${\small{\bold{\purple{\underline{Number\: of\: toffees =\: 30}}}}}$

Henceforth, the number of toffees she give away is 30 toffees.
