ANSWERS
1.D
2. D
Let the three integers be x, x + 2 and
x + 4.
Then, 3x = 2(x + 4) + 3
x = 11.
Third integer = x + 4 = 15.
3.B
Let the ten's digit be x and unit's
digit be y.
Then, (10x + y) - (10y + x) = 36
9(x - y) = 36
x - y = 4
4.B
5.B
6.D
Let the ten's digit be x and unit's
digit be y.
Then, x + y = 15 and x - y = 3
or y - x = 3.
x + y = 15 and x -
y = 3, we get: x = 9, y = 6.
x + y = 15 and y -
x = 3, we get: x = 6, y = 9.
number is either 96 or 69.
the number cannot be determined.
7.A
8.D
Let the ten's digit be x and unit's
digit be y.
number = 10x + y.
Number obtained by interchanging the
digits = 10y + x.
(10x + y) + (10y + x) = 11(x + y),
which is divisible by 11.
9.A
10.A
Let the number be x.
Then, x + 17 = 60/X
x^2 + 17x - 60 = 0
(x + 20)(x - 3) = 0
x = 3.
