the value of that gift is.​

Answer 1

Answer:

Step-by-step explanation:

Savings are in ratio = 4:5

If k be common factor then their savings are 4k and 5k .

A spends 1/3 of his savings. So his share is 4k/3.

After purchasing B lefts with 145/-. So, (5x-145) is the amount B spent. Means 4x/3 : (5x - 145) = 3:4

If m be common factor,

4x/3=3m -----------(1)

And

5x-145 = 4m ---------(2)

So X = 9m/4. From (2)

45m/4 - 145 = 4m

29m/4 = 145

m=20

Now find X and do the rest and get the solution.
