No.of Lucky students = 0.8x × 60% = 0.8x × 0.6 = 0.48x
According to question,
0.48x = 1200
x = (1200 ×100)/048
x = 2500

প্রশ্নঃ X sells a product to Y and makes a profit of 25%. Y sells it to Z at a loss of 20%. If Z buys it for Tk. 140, what is X's purchase price?
বর্ণনাঃ
Let,
X's purchase price = a
X's selling price = a + a × 25a% = 1.25a
= Y's purchase price
Y's selling price = 1.25.a - 1.25a × 20%
= 1.25a - 1.25a ×20/100
= 1.25a - 0.25a
= a = Z's purchasing price = 140
