Question

Of three boxes the first and second together contain rupees 400, second and third rupees 475 and the first and the third rupees 625. find the amount in each box.

Answer 1

let the 1,2,3 box be a, b, c respectively
Now, ATQ
a+b=400.....(i)
b+c= 475 .....(ii)
a+c = 675 ...(iii)
b+c=475
c= 475-b....(iv)
putting iv in iii we get
a + 475-b = 625
therefore, a-b = 150 .....(v)
adding v from i we get
a+b= 400
a-b= 150
a= 275 then we will get b= 125
c= 350

Answer 2

Answer:

Step-by-step explanation:

let the 1,2,3 box be a, b, c respectively

Now, ATQ

a+b=400.....(i)

b+c= 475 .....(ii)

a+c = 675 ...(iii)

b+c=475

c= 475-b....(iv)

putting iv in iii we get

a + 475-b = 625

therefore, a-b = 150 .....(v)

adding v from i we get

a+b= 400

a-b= 150

a= 275 then we will get b= 125

c= 350
