Question

Nisha dividds her collection of 720 stemps among his freind ravi puja swati in the ratio 5:4:7 how many stemps did each recive

Answer 1

It is given that the ratio of stamps divided between Ravi, Puja anf Swati is 5 : 4 : 7.


Now,
Let the stamps of Ravi be 5x
Stamps of Puja be 4x
Stamps of Swati be 7x


As the stamps are divided by Nisha who total 720 stamps.

Hence,
Total stamps ( or, stamps of Nisha ) = stamps of Ravi + stamps of Puja + stamps of Swati


From above, we have the number of stamps of Ravi, Puja and Swati. Then, substituting the values in terms of x.

= > 720 = 5x + 4x + 7x

= > 720 = 16x

= > 720 / 16 = x

= > 45 = x



Now,
Substituting the value of x :

• Stamps of Ravi = 5x = 5( 45 ) = 225
• Stamps of Puja = 4x = 4( 45 ) = 180
• Stamps of Swati = 7x = 7( 45 ) = 315



Thus,
The number of stamps of Ravi is 225 ,
number of stamps of Puja is 180 and the number of stamps of Swati is 315.

Answer 2

Answer:

Ravi :- 225

Puja : 180

Swati : 315

Step-by-step explanation:

Let the ratios of stamps be x

Nisha divides her collection of 720 Stamps among his friend

Ravi gets 5x ---> 1

Puja gets 4x ----> 2

Swati gets 7x -----> 3

Total we have given 720 Students . For Finding x add their ratios

5x + 4x + 7x = 720

9x + 7x = 720

16x = 720

x = $\frac{720}{16}$

x = 45

Find Each friend Stamps which they recieve by putting the value of x in eq (1) , (2) and (3)

Ravi gets 5x

5 * 45

= 225

Puja gets 4x

4 * 45

=  180

Swati gets 7x

7 * 45

= 315
