Let the least price value be Rs x
The next prizes will be x+20, x+40, x+60, x+80, x+100, x+120
The sum of all prizes = Rs700
x +x+20+x+40+x+60+x+80+x+100+x+120 = 700
7x + 420 = 700
7x = 280
x = 40
Prizes are 40, 60, 80, 100, 120, 140, 160
Least value of the prize is Rs 40
The next prizes will be x+20, x+40, x+60, x+80, x+100, x+120
The sum of all prizes = Rs700
x +x+20+x+40+x+60+x+80+x+100+x+120 = 700
7x + 420 = 700
7x = 280
x = 40
Prizes are 40, 60, 80, 100, 120, 140, 160
