उत्तर

Fuel Old prices/
litre (in Rs)
New price/
litre (in Rs)
% Decrease
Petrol / L 45.62 40.62 10.96%
Diesel / L 32.86 30.86 6.09%
LPG/14.2kg 304.70 279.70 8.20%

For Petrol/L,

Old price = ₹ 45.62

New price = ₹ 40.62

Decrement in price = ₹ 45.62 – ₹ 40.62 = ₹ 5

∴ Decrease % = `5/45.62 xx 100`

= `50000/4562`

= 10.96%

For Diesel/L,

Old price = ₹ 32.86

New price = ₹ 30.86

Decrement in price = ₹ 32.86 – ₹ 30.86 = ₹ 2

∴ Decrease % = `2/32.86 xx 100`

= `200/32.86`

= 6.0869

= 6.09%

For LPG,

Old price = ₹ 304.70

New price = ₹ 279.70

Decrement in price = ₹ 304.70 – ₹ 279.70 = ₹ 25

∴ Decrease % = `25/304.70 xx 100`

= `2500/304.70`

= 8.20%
