I. matches of first player with other 5 players

II. matches of second player with 4 players other than the first player

III. matches of third player with 3 players other than the first player and second player.

IV. matches of fourth player with 2 players other than the first player, second player and third player.

V. matches of fifth player with 1 player other than the first player, second player, third player and fourth player.

So total matches will be 5+4+3+2+1 = 15

Let Sunita's present age = x years

Then Reena present age = 2x years

Three years ago

(2x-3) = 3(x-3)

2x - 3 = 3x - 9

or x = 6

Reena age = 2x = 2*6 = 12 year.

Generally we may commit mistake of dividing 1200/15.

But out of 16 persons there is one captain.

so, it will be 1200/16 = 75

Let the number of bananas in the second bunch be x.

Then, the number of bananas in the first bunch

= x + 1/4 x

= 5/4 x

So,

5/4 x - x = 3

=> 5x - 4x = 12

x = 12

Number of bananas in first bunch

= 5/4 * 12 = 15

First of all, calculate LCM of 5, 6, 7 and 8 which is 840.

Suppose Number is K

then 840 * K + 3 is divisible by 9.

If K = 1, number = (840 × 1) + 3 = 843 which is not divisible by 9

If K = 2, number = (840 × 2) + 3 = 1683 which is divisible by 9

So 1683 is correct answer.

Clearly, we have :

B-3 = E ...(i)

B + 3 = D ...(ii)

A+B = D + E+10 ...(iii)

B = C + 2 ...(iv)

A+B + C + D + E= 133 ...(v)

From (i) and (ii), we have : 2 B = D + E ...(vi)

From (iii) and (vi), we have : A = B + 10 ...(vii)

Using (iv), (vi) and (vii) in (v), we get:

(B + 10) + B + (B - 2) + 2B = 133 <=> 5B = 125 <=> B = 25.

Let x and y be the ten's and unit's digits respectively of the numeral denoting the woman's age.

Then, woman's age = (10X + y) years; husband's age = (10y + x) years.

Therefore (10y + x)- (10X + y) = (1/11) (10y + x + 10x + y)

<=> (9y-9x) = (1/11)(11y + 11x) = (x + y)<=>10x = 8y<=>x = (4/5)y

Clearly, y should be a single-digit multiple of 5, which is 5.

So, x = 4, y = 5.

Hence, woman's age = 10x + y = 45 years.

Since one of the numbers on the dial of a telephone is zero, so the product of all the numbers on it is 0.
