Let the price of a pant and a t-shirt be Rs. x and Rs. y respectively.   Then, 3x + 6y = 1500 .... (i)   and x + 12y = 1500 .... (ii)   Divide equation (i) by 3, we get the below equation.   = x + 2y = 500. --- (iii)   Now subtract (iii) from (ii)   x + 12y = 1500 (-)   x + 2y = 500   ----------------   10y = 1000   ----------------   cost of 8 t-shirts = 8*100=
