Answer 1

Answer:

C. Rs 300

Step-by-step explanation:

Let the amount that parzon have be x and gazi has be y

From given question, equation will be:-

x/5=y/7--->7x=5y---->x=5y/7

Given:

x+y=720

But 5y/7+y=720

LCM=7

12y/7=720

12y=5040

y=5040/12=420

So Gazi has 420 Rs

Then Parzan will have 720-420=300 Rs

So Parzan will have 300 Rs

Answer is C.

Hope it helps you!

Answer 2

Answer:

The amount of money that Parzan has is Rs. 300.

Step-by-step explanation:

Parzan and Gazi together have Rs 720.

1/5 of Parzan's wealth is equivalent to 1/7 of Gazi's wealth.

Let the amount that Parzan has be x and Gazi has be y

From the given question, the equation will be:-

x/5 = y/7

Simplifying it, we get

7x = 5y

So, x = 5y/7

Given in the question:

x+y=720

But 5y/7+y=720

LCM is 7

So, 12y/7=720

Thus, 12y = 5040

y = 5040/12 = 420

So Gazi has Rs 420

Then Parzan will have 720 - 420 = Rs 300

So Parzan will have Rs. 300

Therefore, the correct option is C.
