Thank You. *Please Solve this Mathematics Problem. |
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= [B]2.5[/B] Old Price of 1 kg Sugar = 2.5 New Price of 1 kg Sugar = 2.5*1.5 = 3.75 |
