please guys solve this in 5 minutes

a shopkeeper has 5 red pen , x green pen and 8 blue pen if the range is the multiple of 7 and x then what is the maximum possible value of x​

Answer 1

Answer:

Step-by-step explanation:

Since, the two digit prime numbers are,

11, 13, 17, 19,.................89, 93, 97,

Given,

The numbers of red pen = 5,

Black pen = 8,

Also, the green pen = x,

Where, x is a two digit prime number,

Such that, 5 + 8 + x is divisible by 7 ( ∵ the range of the data is multiple of 7 ),

Since, we have to find maximum value of x,

If x = 97,

5 + 8 + 97 = 110 is not divisible by 7,

If x = 93,

5 + 8 + 93 = 106 is not divisible by 7,

If x = 89,

5 + 8 + 89 = 102 is a multiple of 7,

Hence, the maximum value of x is 89,

That is, the sum of digits of maximum possible value of x is 17.
