Answer:
Step-by-step explanation:
Let us represent:
Number of rupees that:
Sara has = x
Hina = y
Arsalan = z
Sara,Hina and arsalan has rupees 930
x + y + z = 930..... Equation 1
if Sara has 7 more than Hina
x = y + 7
y = x - 7
Arsalan has 3 times what sara has
z = 3x
We substitute x - 7 for y and 3x for z in Equation 1
x + y + z = 930..... Equation 1
x + x - 7 + 3x = 930
5x - 7 = 930
5x = 930 + 7
5x = 937
Step-by-step explanation:
x = Alice's money
y = Mio's money
z = Grace's money
x + y + z = sum
there are originality 5+4+3 = 12 parts of the money shared between them.
x = 5/12 sum
y = 4/12 sum
z = 3/12 sum
after the money transfer we are only having 4+3+2 = 9 parts of the same money distributed.
so, we are dealing with 1/9 parts.
let's bring everything to 1/36 to be able to truly compare things.
therefore
x = 15/36 sum
y = 12/36 sum
z = 9/36 sum
15/36 sum + 10 = 16/36 sum
because 4/9 = 16/36
10 = 1/36 sum
sum = 10×36 = £360
so, together they have £360.
and they had before the £10 transfer £150, £120, £90.
after the £10 transfer they had £160, £120, £80.
