Question : 1
The least number among $4/9,√{9/49}$, 0.45 and $(0.8)^2$ is
a) 0.45
b) $(0.8)^2$
c) $√{9/49}$
d) $4/9$
Answer »Answer: (c)
Decimal equivalents :
$4/9$ = 0. 4: $√{9/49}$ = $3/7$ = 0.43
0.45 : $(0.8)^2$ = 0.64
∴ Least number = 0.43 = $√{9/49}$
Question : 2
When 335 is added to 5A7, the result is 8B2. 8B2 is divisible by 3. What is the largest possible value of A ?
a) 1
b) 4
c) 2
d) 8
Answer »Answer: (b)
5A7 + 335 = 8B2
⇒ A → 1, 2, 3, 4, 5 &
B → 5, 6, 7, 8,9
8B2 is exactly divisible by 3.
∴ 8 + B + 2 = multiple of 3
∴ B = 5 or 8 ⇒ A = 1 or 4
Question : 3
The least number of five digits which has 123 as a factor is
a) 10081
b) 10063
c) 10086
d) 10037
Answer »Answer: (c)
The smallest number of 5 digits = 10000
Remainder on dividing 10000 by 123 = 37
∴ Required number = 10000 + (123 – 37) = 10086
Question : 4
Sum of three fractions is 2$11/24$ . On dividing the largest fraction by the smallest fraction, $7/6$ is obtained which is $1/3$ greater than the middle fraction. The smallest fraction is
a) 5/6
b) 3/7
c) 3/4
d) 5/8
Answer »Answer: (c)
Let the three fractions be p, q and r,
where p < q < r.
According to the question,
$r/p$ = $7/6$ ⇒ r = $7/6$ p
Again, middle fraction
= q = $7/6$ - $1/3$ = ${7-2}/6$ = $5/6$
∴ p+q+r = 2$11/24$
⇒ p + $5/6$ + $7/6$p = $59/24$
⇒ p+${7p}/6$ = $59/24$ - $5/6$
⇒ ${6p+7p}/6$ = ${59-20}/24$ = $93/24$
⇒ 13p = $39/24$×6 = $39/4$
⇒ p = $39/{4×13}$ = $3/4$
Question : 5
Which of the following is the largest fraction ? $6/7, 5/6, 7/8, 4/5$
a) $5/6$
b) $7/8$
c) $4/5$
d) $6/7$
Answer »Answer: (b)
The decimal equivalents of :
$6/7 = 0.857, 5/6 = 0.833$
$∴7/8 = 0.875, 4/5 = 0.8$
Obviously, 0.875 is the greatest.
$7/8$ is the largest fraction.
Question : 6
Which of the following fraction is the smallest? $7/6, 7/9, 4/5, 5/7$
a) $4/5$
b) $5/7$
c) $7/ 9$
d) $7/6$
Answer »Answer: (b)
$7/6$ = 1.166 ; $7/9$ = 0.777; $4/5$ = 0.8 and $5/7$ = 0.714
Therefore, the smallest number is $5/7$
