Answer: Option D

Explanation:

Based on the options provided, the assumption that underlies the argument in the passage is:

A decrease in demand for most banned products in 2007 was not the sole cause of the drop in their price.

This assumption suggests that there were other factors besides the decrease in demand that contributed to the drop in the price of banned products in 2007. The argument relies on the idea that the decrease in supply or other factors played a significant role in causing the observed decrease in price, rather than solely relying on the decrease in demand.

Explanation:

ATQ, B - A = C - B

= > 2B = A + C

Now, A + B + C = 30 x3 = 90

= > B + (A + C) = 90

= > B + 2B = 90

= > 3B = 90 :: B = 30

D's age = 30 + 40 = 70

B + D = 70 + 30 = 100 (Ans) .

Answer: Option B

Explanation:

A + B + C + D + E = 40 × 5 = 200
A + B = 35 × 2 = 70
C + D = 42 × 2 = 84
Therefore,
E = (A + B + C + D + E) - (A + B + C + D)
E = 200 - 70 - 84
E = 46 years.

Answer: Option D

Explanation:

দেওয়া আছে, 10 জন ছাত্রের গড় বয়স = 20

∴ 10 জন ছাত্রের গড় বয়স = 10 × 20

= 200 বছর

আবার, 2 জন নতুন ছাত্র আসার পর ,

12 জন ছাত্রের গড় বয়স = (20+2) বছর

∴ 12 জন ছাত্রের মোট বয়স = (12 × 22 ) বছর

নতুন ২ জন ছাত্রের মোট বয়স = (264 - 200)

= 64 বছর

∴ 2 জন ছাত্রের গড় বয়স = 64/2 = 32 বছর

Answer: Option B

Explanation:

3 years ago their average age was = 27 years

At present their average age = ( 27 + 3) = 30 years

At present the summation of their age = 30×3 = 90 years

Again,

5 years ago, the average age of child and wife was = 20 years

At present their average age = 20 + 5 = 25 years.

At present the summation of their age = 25×2 = 50 years

So, at present the husbands age = 90 - 50 = 40 years
