Question

for each successive kilometre.
5. One kilogram of tea and 4 kg of sugar together cost * 220. If the price of sugar increases
by 50% and the price of tea increases by 10% the cost would be 266. Find the original
cost per kilogram of each.


can any one solve​

Answer 1

x+4y=220

(x+10x/100) +4(y+50y/100)=266=> 11x+60y=2660. (eq.1)

11(x+4y)=11*220=> 11x+44y=2420. ( eq.2 )

Now eq. 1 - eq.2

y=15

x=220-4y

x=160
