Question

after spending 2/5 of her money on a toy aeroplane Sita had rupees 42 left how much money in the sita have at first​

Answer 1

Answer:

Let x = original amount of money

Since we know that because "Mary spent 2/5 of her money", she'll have 3%2F5 of her money left (since 1-2%2F5=3%2F5). So she has %283%2F5%29x dollars left. Now we also know that she has "$60 left", so this means that %283%2F5%29x=60

%283%2F5%29x=60 Start with the given equation.

3x=5%2860%29 Multiply both sides by 5.

3x=300 Multiply.

x=%28300%29%2F%283%29 Divide both sides by 3 to isolate x.

 

x=100 .

Answer:

So the answer is x=100

This means that Mary had $100 originally.

Answer 2

You see,sita has spent ⅖ of her money.so she has (1-⅖=⅗) of her money.she has ⅗ of her money.

Process:-

⅗= rs.42

so,now I have to find out how much money she has spent.

Then,42÷3= rs.14

If ⅕=rs.14

then (5/5)=14×5=70

so,the answer is she had rs.70
