Question

the value of zaltans house has incresed 7% . his house is now £74900 . how much was the house before the increase

Answer 1

Answer:

£70,000

Step-by-step explanation:

Let the initial value be x

New value = (100+7)% of initial value

74900 = 107% of x

74900 = 107 / 100  of x

Multiply both sides by 100

74900×100 = 107x

107x = 7490000

Divide both sides by 107

107x/107 = 7490000 ➗ 107

x = £70,000

Answer 2

Answer:

Step-by-step explanation:

Let the previous value of the house be represented by x

New value = ((%inrease/100) × previous value)+ previous value

74,900= ((7/100) × x) +x

74900= (7x/100)+x

74900= 107x/100

x= 74900×100÷107

X=70,000

The previous value is £70,000
