Rate at which each pumpkin is sold = $5 Rate at which each squash is sold = $3 Let us assume the number of pumpkins sold in a day = x Then The number of squash sold on that day = x + 6 Total amount of sales on that day = $98 Then 5x + 3( x + 6) = 98 5x + 3x + 18 = 98 8x = 98 - 18 8x = 80 x = 80/8 = 10 So The number of pumpkins sold = 10 The number of squash sold = x + 6 = 10 + 6 = 16
Vol of water required to fill up the tub = 12-3 = 9 Rate of water per min = 3 -1.5 = 1.5/min Using the formula vol = rt t = v/r t = 9/1.5 = 6 time taken = 6 mins
