Let x be the unknown number.

40% is 0.4 as a decimal.

x + 0.4x = 700
1.4x = 700
x = 700/1.4
x = 500

Let n be the number.

n (1 + 40%) = 700
1.4n = 700
n = 700/1.4
n = 500

The number is 500.

Let required number be x. Then 700 = 140x/100, ie., x = 7000/14 = 500.

140% is 700

so, 1% is 700/140 => 5

Hence, 100% is 500
