[1,070 + 0.07(29,000 - 25,000)] - [1,070 + 0.07(26,000 - 25,000)]

0.07(4,000) - 0.07(1,000)

0.07(3,000) = 210.

A. vegetables are subject to downward price control in city area by the government
B. City dwellers purchase vegetable produced only in the city area
C. Vegetables are mostly common item of every meal of a city dweller
D. Abundantly produced rural vegetables area not allowed to sell in city area

View Answer	Favorite Question

Answer: Option D

Explanation:

To weaken the claim that "Price of vegetables is very high in city area in comparison to that in rural area," we need to find a fact that contradicts or undermines this claim. Let's analyze the options provided:

A. There is least demand for vegetable in city area.
This fact supports the claim that the price of vegetables is high in the city area because low demand could contribute to higher prices due to limited supply and higher transportation costs.

B. Vegetables are subject to downward price control in city area by the government.
This fact weakens the claim by suggesting that the government has implemented measures to control and regulate vegetable prices in the city area, which could result in lower prices.

C. City dwellers purchase vegetable produced only in the city area.
This fact does not weaken the claim but rather supports it. If city dwellers exclusively purchase vegetables produced in the city area, it implies a limited supply, which can contribute to higher prices.

D. Vegetables are mostly a common item of every meal of a city dweller.
This fact does not weaken the claim but rather supports it. If vegetables are a common item in every meal of city dwellers, it suggests high demand, which can contribute to higher prices.

Answer: Option D

Explanation:

Let speed of the boat is u kmph

Speed of the stream is v = 3 kmph

Time taken t = 39 min = 39/60 hour

Distance s = 13 km

We have

u - v = s/t

u - v = 13/(39/60) = (13×60)/39 = 20

= > u - 3 = 20

= > u = 20 + 3 = 23

Ans 23 kmph.

Answer: Option A

Explanation:

The maximum number of marbles in a single package is the HCF (Highest Common Factor) of 72 and 108.

72 = 2 x 2 x 2 x 3 x 3

108 = 2 x 2 x 3 x 3 x 3

∴HCF of 72 and 108 is = 2 x 2 x 3 x 3 = 36.

So the max number of marbles that can go into a package is 36.

ans: 36

View Answer	Favorite Question

Answer: Option C

Explanation:

Everybody does 9 handshakes - but then they are counted twice, so 10 * 9 /2 = 45.

Alternative calculation:

Person no 1 does 9 handshakes

Person no 2 does 8 - he already has shaken hands with no1

And so on …

person no 9 does 1 handshake with person no 10

Btw person no10 has already shaken everybody’s hand, ok

So we get 9 + 8 + … + 1

The seven years old Gauß might tell you that this is 10 * 9 / 2 = 45
