D. TK. 1600
E. None of these

View Answer	Favorite Question

Answer: Option A

Explanation:

Spent on books = 1/3

Spent on clothing = 1/2 of (1 - 1/3) = 1/2 × 2/3 = 1/3

Spent on food = 3/4 × { 1 - (1/3 + 1/3)} = 3/4 × (1 - 2/3) = 3/4 × 1/3 = 1/4

Left over = 1 - (1/3 + 1/3 + 1/4) = 1 - (4 + 4 + 3)/12 = 1 - 11/12 = 1/12

Now, 1/12 ≡ 500 TK

Then, she started with 500×12 = 6000 TK

A. 3 years
B. 10 years
C. 20 years
D. 25 years

View Answer	Favorite Question

Answer: Option B

Let,

Rony age = R, Jony age = J

এখানে বর্তমানে,

R = J - 20

বা, J = R + 20

10 বছর পর,

R + 10 = (J + 10)/2

বা, 2R + 20 = J + 10

বা, 2R + 20 = R + 20 + 10

so, R = 10

Answer: Option B

Explanation:

Let, he bought x kg at 50/kg rate

y kg at 60/kg rate

So, the cost price = 50x + 60y

and sell price = 70 ( x + y)

Now, the profit was 20%

if cost price is 100 selling is 120 tk

if cost price (50x + 60y) selling is 120( 50x + 60y)/100

120(50x + 60y)/100 = 70(x + y)

60x + 72y = 70x + 70y

2y = 10x

5x = y

x/y = 1/5

x : y = 1 : 5

View Answer	Favorite Question

Answer: Option C

Explanation:

25 TK এর মধ্যে 30 paisa tax.তাহলে original purchase হয়ছে( 25 - .30) বা 24.7 টাকায় যদি এর মধ্যে x টাকার হয় tax free item তবে প্রশ্নমতে বাকি জিনিসের উপর 6% ট্যাক্স।

(24.7 - x) × o.o6 = 0.30

1.482 - 0.06x = 0.30

1.482 - 0.30 = 0.06x

0.06x = 1.182

x = 19.70
