Default Please this Mathematics Problem related to %

1 kg of tea and 4 kg of sugar cost 35 but if sugar rises by 50% and tea by 10% they would cost 42.50. Find the price per kg of sugar.

T: Price of 1 kg tea
S: Price of 1 kg sugar
4S: Price of 4 kg of sugar

T+4S = 35 Eqn. A
T = 35 -4S

1.1T: Price of 1 kg tea after 10% increase
1.5S: Price of 1 kg sugar after 50% increase

1.1T + 4(1.5S) = 42.5
1.1T + 6S = 42.5 Eqn.B

**Solve simultaneously Eqns. A and B

1.1(35-4S) + 6S = 42.5
38.5 -4.4S + 6S = 42.5
1.6S = 4
S = 4/1.6= 2.5

Old Price of 1 kg Sugar = 2.5
New Price of 1 kg Sugar = 2.5*1.5 = 3.75
