Let the price of a pant and a t-shirt be Rs. x and Rs. y respectively.   Then, 3x + 6y = 2250 .... (i)   and x + 12y = 2250 .... (ii)   Divide equation (i) by 3, we get the below equation.   = x + 2y = 750. --- (iii)   Now subtract (iii) from (ii)   x + 12y = 2250 (-)   x + 2y = 750   ----------------   10y = 1500   ----------------   y= 150   cost of 8 t-shirts = 8*150=
