Answer: Option C

Explanation:

4y - 3x = 5

4y = 5 + 3x

y = 5 + 3x /4

শর্তমতে, (5 + 3x)/4 > 100

5 + 3x > 400

3x > 395/3

x > 131.67

যেহেতু x এর মান হবে ক্ষুদ্রতম পূর্ণসংখ্যা

x = 132

Answer: Option C

Explanation:

Hints: Let cost price of an article x

When SP is 340 Tk, then gain % = 340 - x /x ×100

When SP is increased, if 5% more is gained by selling an article for 350 TK. than by selling if for 340 TK.

Then, [ (350 - x)/x ×100] - [ (340 - x)/x × 100 ] = 5

100/x [ 350 - x - 340 + x ] = 5

100/x [10] = 5

x = 1000/5 = 200 TK.

Answer: Option B

Explanation:

Area of rectangular RUG = (base)(height) = (9)(12) = 108

This RUG covers 60% of the FLOOR

In other words, 108 = 60% of the area of the FLOOR

Or we can write: 108 = 0.6(area of FLOOR)

So, 108 /0.6 = area of FLOOR

Evaluate to get: 180 = area of FLOOR
