Question

Section 'A'
Question numbers 1 to 10 carry I mark each. For each of these questions four alternative choices have
been provided of which only one is correct. Select the correct choice.
1. The largest number which divides 70 and 125, leaving remainders 5 and 8. respectively.
(a) 13.
(b) 65.
(c) 875.
(d) 1.750
2. The decimal expansion of the rational number will terminate after:
1250
(c) 3
(a) one decimal place. (b) two decimal places. (c) three decimal places. (d) four decimal places
3. The number of polynomials having zeroes as -2 and 5 is:
(a) 1
(b) 2
(d) more than 3
4. Graphically, the pair of equations
6x - 3y + 10 = 0
2x - y +9=0
represents two lines which are
(a) intersecting at exactly one point
(b) intersecting at exactly two points
(c) coincident
(d) parallel
OR
One equation of a pair of dependent linear equations is -5x + 7y = 2. The second equation can be :
(a) 10x + 14y + 4 = 0
(b) - 10x - 14y + 4 = 0
(c)-10x + 14y + 4 = 0
(d) 10x - 14y = - 4​

Answer 2

Answer:

1)a

Hi ,

__________________________

The largest number by which x , y

divisible and gives the remainder a ,

and b is

the HCF of ( x - a ) and ( y - b)

__________________________

According to the given problem ,

The largest number which divides

70 and 125 leaving remainders 5 and

8 respectively are

HCF of ( 70 - 5 ) = 65 and

( 125 - 8 ) = 117

65 = 5 × 13

117 = 3 × 3 × 13

HCF ( 65 , 117 ) = 13

Required number is 13.

2)The question is incomplete

3) More than 3

4) d

3=3 not equal to 10/9

or

4) d

1/2=1/2=1/2
