Arjun have ₹30
Sejal have₹50

Answer 2

Answer:

Arjun has Rs.62 and Sejal has Rs.34

Step-by-step explanation:

Let us suppose Arjun has Rs.x and Sejal has Rs.y

If arjun gives ₹ 30 to sejal, the sejal will have twice the money left with arjun.

$2(x-30)=y+30$ ----A

if sejal gives ₹ 10 to arjun, the arjun will have thrice as much as is left with sejal.

$3(y-10)=x+10$ ---B

Solve A and B

Plot lines A and B

$2(x-30)=y+30$ -- Black

$3(y-10)=x+10$ --- Red

Intersection will provide the answer

(x,y)=(62,34)

So, Arjun has Rs.62 and Sejal has Rs.34
