7. Mathematics: 15×2 = 30
a. A man sells an article at a profit of 25%. If he had bought it
at 20% less and sold it for Tk. 10.50 less, he would have
gained 30%. Find the cost price of the article.
Solution:
Suppose, the cost price of the article is Tk 100x
So, the selling price of the article is = Tk 100x + 25x = Tk
125x.
If he had bought it for 100x - 20x = 80x, and sold it for
(125x-10.50), the gain percentage would have been 30%.
So,
80x × 0.30 = (125x-10.50) - 80x
24x = 45x - 10.50
21x = 10.50
x = 10.50/21 = 0.50
So, the cost price of the article is = 100x = 100×0.5 = 50 tk
ans: 50 tk.
--------------------------------------------------
b. A and B can do a piece of work in 18 days, B and C can do
it in 24 days, A and C can do it in 36 days. In how many days
will A, B and C finish it, working together and separately?
Solution:
1 day's work of A+B = 1/18 ---------- (i)
1 day's work of B+C = 1/24 ------------ (ii)
1 day's work of C+A = 1/36 ------------- (iii)
------------------------------------
1 day's work of 2(A+B+C) = 1/18 + 1/24 + 1/36 = 9/72 = 1/8
1 day's work of A+B+C = 1/8*2 = 1/16 ------- (iv)
Together they can do it in 16 days.
(iv) - (i) =>
1 day's work of C = 1/16 - 1/18 = 1/144
So, C alone can do it in 144 days.
(iv) - (ii) =>
1 day's work of A = 1/16 - 1/24 = 1/48
So, A alone can do it in 48 days.
(iv) - (iii) =>
1 day's work of B = 1/16 - 1/36 = 5/144
So, B alone can do it in 144/5 = 28.8 days.
