Question : 11 [SSC CGL 2002]
Which of the following fraction is the smallest? $8/15, 14/33, 7/13, 11/13$
a) $11 /13$
b) $14/33$
c) $7/13$
d) $8/15$
Answer »Answer: (b)
$8/15, 14/33, 7/13, 11/13$
$8/15$ = 0.53$\ov{3}$
$14/33$ = 0.$\ov{42}$
$7/13$ = 0.538
$11/13$ = 0.846
∴$11/13>7/13>8/15>14/33$
Question : 12
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 : 13 [SSC CGL Tier-II 2013]
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 : 14 [SSC CPU 2012]
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 : 15 [SSC CGL Prelim 2004]
The smallest number of five digits exactly divisible by 476 is
a) 10476
b) 10472
c) 10000
d) 47600
Answer »Answer: (b)
The smallest number of 5 digits = 10000
Now,
$10000/476$=21$4/476$
∴Required number = 10000 + (476 – 4)
= 10000 + 472 = 10472
