Given:
John had to pay a combined electric and gas bill $150.
The electric portion of the bill was $90.
To find:
The ratio of money spent on electric to that on gas.
Solution:
Let x be the amount of gas bill.
The electric portion of the bill was $90 and John had to pay a combined electric and gas bill $150. So,



The gas portion of the bill was $60.
The ratio of money spent on electric to that on gas is:




Therefore, the ratio of money spent on electric to that on gas is 3:2.
Total tax paid = 1440
Tax rate = Rs 2 per Rs 100
ATQ
1440 ÷ 2
= 720
720 × 100
Rs 72,000
His income is Rs 72,000

x=185
you need to add a positive 62 from each side so -62+62=0 and 123+62=185
therefore, x=185
