7 boxes & 24 Balls.
Let, n = No. of boxes ; m = No. of fruits
3n+3 = m---------->(1)
4(n-1)= m---------->(2)
=>4n-4 = 3n+3;
=>4n-3n = 4+3
n = 7
Put n=7 in eqn(1)
=> 3(7)+3 = m
21+3 = m
m = 24;

Number of boxes = 7 and fruits = 24

Michael Faraday invented Electric Generator in 1831.

• The operating principle of electromagnetic generators was discovered in the years of 1831–1832 by Michael Faraday.

• The principle later called Faraday's law, is that an electromotive force is generated in an electrical conductor which encircles a varying magnetic flux.

Let 'Y' be the youngest player.

The last song can be sung by any of the remaining 3 players. The first 3 players can sing the song in (3!) ways.

The required number of ways = 3(3!) = 4320.

Let father's age be x year and son's age be y year.

According to question,

2(x+y) = 8y _______(I)

and (x+y)/2 = 30

=> x+y = 60 years__________(II)

From equation (I) and (II)

8 y = 120

y = 15 years,

Hence x = 45 years.

Given that to find 15 of 80

=> What % of 80 is 15

Let it be 'p'

=> p% of 80 = 15

=> $$\begin{gathered} p x 80100 = 15 \\ ⇒p = 15 x 10080 \\ ⇒p = 150080 = 18.75 \end{gathered}$$

Therefore, 15 is 18.75% of 80 => 18.75% of 80 = 15

Example::

Now, in the similar way we can find 15% of 80 =?

=> 15x80/100 = p

=> p = 4 x 3 = 12

Therefore, 15% of 80 = 12

Moti Masjid was built by the Mughal emperor Aurangzeb from 1659-1660. The Moti Masjid is a white marble mosque inside the Red Fort complex in Delhi, India.

From the above figure, we can say that there is the same amount of alcohol in one regular beer (340 ml/12 oz, 5% alcohol), one glass of wine (140 ml/5oz, 12% alcohol), one glass of fortified wine (85 ml/3oz, 20% alcohol) and one shot of spirits (45 ml/1.5 oz, 40% alcohol).

Hence, the given statement whiskey has more alcohol than wine is TRUE.
