Let the original price be 10x Rs per kg
New price = 8x Rs per kg
120/8x - 120/10x = 3
MULTIPLY BY 40x
600 - 480 = 120x
120 = 120x
x = 1
10x = Rs 10 per kg ANSWER
CHECK
120/10 = 12 kg
120/8 = 15 kg
sugar be x rupees per kg. He buys y kg
so we get xy=120
rate is reduced 20 %. i.e 1/5. The new rate will be x-x/5= 4x/5
he get y+3 kg suger
we get
now
4x/5(y+3)= xy
4/5 (y+3) = y
Whe solved
4y+12=5y
y=12 He buys 12 kg
The rate will be
x 12 = 120
x=10
Rate 10Rs/per kg.
x=original price of sugar
0.2x=3*120
x=1800
