As per your question, total cost of watermelon should end with either 5(for odd quantity) or 0(for even quantity).

If the quantity of watermelon is odd, then the total cost value of pineapple should end with 3 and this is not possible when the cost of pineapple is ₹7.

So let's come to conclusion that the count(quantity) of watermelon should be any one of 0, 2, 4, 6.

If count of watermelon is 6: It will cost ₹30 and for remaining ₹8, we can buy 1 pineapple but still ₹1 will not be utilised. So 1 pineapple is not possible

If count of watermelon is 4: It will cost ₹20 and for remaining ₹18, we can buy 2 pineapple with ₹4 not being utilised. So 2 pineapple is also not possible.

If count of watermelon is 2: It will cost ₹10 and for remaining ₹28, we can buy 4 pineapple with all amount being utilised. We can buy 4 pineapple along with with 2 watermelon for ₹38.

If count of watermelon is 0: It will cost you ₹0 and for remaining ₹38, we can buy 5 pineapple with ₹3 being not utilised. So 5 pineapple is also not possible.

So the answer is 4 pineapple.

Mr Ronaldo earns $54,800 annually. If he pays the government with an income tax rate of 9%, then how much will he pay in just in
Goryan [66]

The total income tax paid by Mr. Ronaldo is $4932

A fraction of 100 can be used to express a number or ratio as a percentage. Per 100 is what the word percentage signifies. To denote it, use the symbol "%".

The phrase "income tax" refers to a particular kind of tax that governments levy on money made by people and enterprises under their control.

Given data

Ronaldo earns annually = 54, 800

Tax paid to government = 9%

We have to find the income tax by him =?

Let us consider total income tax paid by Ronaldo = X

⇒ 54,800 x 9% = X

⇒ 54800 x 9/100 =X

⇒ 493200 / 100 =X

X = 4932

Therefore total tax paid by him is $4932

Two trains leave stations 442 miles apart at the same time and travel toward each other. One train travels at 95 miles per hour
Brrunno [24]

(75 + 95) \times x = 442

x =  \frac{442}{75 + 95}  = 2.6

so it takes 2.6 of hours which is the same as 2 hours and 36 minutes for them to reach eachother.
