Answer 2

Answer:

The value of x is 4

Step-by-step explanation:

Step 1: Assume the number to be X

Step 2: To Calculate the value of 40% of 70

Step 3: 40% of 70  

40/100 x 70

=28

Step 4: To Calculate the value of 30% of 80

30/100×80

=24

Now coming to the question

Step 5: Framing an equation is

40% of 70 =X+ 30% of 80

$=\frac{40}{100} \times 70=\mathrm{X}+\frac{30}{100} \times 80$

Step 6: 28 = X + 24  

X=28 - 24

X=4
