NCERT Solutions for Class 8 Maths Chapter 16 Playing with Numbers Exercise 16.2<\/h2>\n

Question 1.
\nIt 21y5 is a multiple of 9, where y is a digit, what is the value of y?
\nAnswer:
\n21Y5 is a multiple of 9
\n\u2234 2 + 1 + y + 5 = 8 + y must be divisible by 9
\n(8 + y) should be 9, 18, 27,… etc.
\nSince y is a digit.
\n8 + y = 9
\ny = 9 – 8 = 1
\n\u2234 The value of y = 1.<\/p>\n

Question 2.
\nIf 31z5 is a multiple of 9, where Z is a digit. What is the value of z? You will find that there are two answers for the last problem. Why is this so?
\nAnswer.
\n31z5 = 3 + l + z + 5 = 9 + z
\n31z5 is divisible by 9
\n\u2234 9 + z must be equal to 9, 18, 27,… etc.
\nZ is a single digit number.
\n9 + z is one of these numbers.
\n9 + z = 9 then z = 0
\n9 + z=18 thenz= 18-9 = 9
\n\u2234 The value of z = 0 or 9.<\/p>\n

Question 3.
\nIf 24x is a multiple of 3, where x is a digit, what is the value of x?
\nAnswer:
\nSince 24x is a multiple of 3, so sum of digits i.e. 6 + x is a multiple of 3.
\n6 + x is one of these numbers: 0, 3,6, 9 12, 15, 18,… But since x is a digit,
\n\u2234 6 + x = 6 or 9 or 12 or 15
\n\u2234 x = 0, or 3 or 6 or 9
\nThe value of x = 0 or 3 or 6 or 9<\/p>\n

Question 4.
\n31z5 is a multiple of 3, where z is a digit, what might be the values of z?
\nAnswer:
\nSum of the digits =3+l+z+5=9+z 9 + z is a multiple of 3
\nSo, 9 + z is one of the numbers: 0, 3, 6, 9, 12, 15,…
\nBut since z is a digit, 9 + z = 9 or 12 or 15 or 18 or 21…
\n\u2234 The Value of z = 0 or 3 or 6 or 9 or 15 or 18.<\/p>\n","protected":false},"excerpt":{"rendered":"
