Question

total price of 1 kg Chiku and 1 kg guava is rupees 70 price of 3 kg Chiku and 2kg guava is rupees 170 then find the price of 1kg Chiku​

Answer 1

Answer:

1kg chicku=rs.30

chicku=c

banana=b

1kg c+1kg b=rs.70

3kg c+2kg b=170

if price of 2 kg of both is equal then =140

but real is 170, difference is 30rs

so price of 1 kg chicku is 30

PROOF:

170-140=40

banana=40

70-30=40

30+40=70

rs.30×3kg+rs.40×2kg =170

rs.90+rs.80=170

so price of chicku will be RS.30/kg
