I think correct option is not given in today's puzzle.

Minimum 5 coins required to get the following 5 sums successfully
35, 46, 53, 69, 77.

coins denominations are 35,46,53,69,77.
or
35,11,7,16,8 ............ 5 coins
but it is not given in options.

so minimum 6 coins.

In today's puzzle, the correct answer option has not been given in my opinion.
The probability that the first box chosen among the three boxes is 1/3.
And the prob. that the ball selected is red 4/7
Thus in aggregate, that the probability that the ball selected at random come from the first box=1/3*4/7=4/21

For this puzzle
The sum of 2 numbers x and y is 10. y(x^2) will be maximum for x = ....

Options.

1) 2
2) 5/2
3) 10/3
4) 20/3
5) 4
6) 28/3
7) 21/4
8) 6
9) 8
10) none of these

Ans. 4

Reason. Given that x+y = 10
For y(x^2) to be maximum we should divide 10 between y and x in such a way that y/1 = x/2 = 10/(1+2)
so x = 20/3, y = 10/3

Answer should be option 10....none of these.
when
x = 20/3, y = 10/3, y(x^2) = (10/3) * (400/9) = 4000/27
when x=10,y=10, then y*(x^2) =10*100= 1000 which is more than 4000/27.

pls check .
