Question: 1

The smallest fraction which should be subtracted from the sum of \$\$1{3}/{4}\$\$, \$\$2{1}/{2}\$\$, \$\$5{7}/{12}\$\$, \$\$3{1}/{3}\$\$ and \$\$2{1}/{4}\$\$ to make the result a whole number is

(A) \$\${185}/{12}\$\$

(B) \$\${18}/{12}\$\$

(C) \$\${1}/{2}\$\$

(D) 7

Ans: A

Sum of given fractions = \$\${7}/{4} + {5}/{2} + {67}/{12} + {10}/{3} + {9}/{4}\$\$

= \$\$({21 + 30 + 67 + 40 + 27} / {12})\$\$ = \$\${185}/{12}\$\$

The whole number just less than \$\${185}/{12}\$\$ is 15.

Let \$\${185}/{12}\$\$ - x = 15. Then, x = \$\$({185}/{12} - 15)\$\$ = \$\${5}/{12}\$\$.

Question: 2

1260 ÷ 15 ÷ 7 = ?

(A) 10

(B) 12

(C) 58

(D) 122

Ans: B

Given expression = 1260 ÷ 15 ÷ 7= 84 ÷ 7 = 12.

Question: 3

\$\$(999{999}/{1000} × 7)\$\$ is equal to

(A) \$\$6633{7}/{1000}\$\$

(B) \$\$6993{7}/{1000}\$\$

(C) \$\$6999{993}/{1000}\$\$

(D) \$\$7000{7}/{1000}\$\$

Ans: C

Given expression = \$\$({1000} – 1/{1000})\$\$ × 7 = \$\$(7000 - {7}/{1000})\$\$ = \$\$6999{993}/{1000}\$\$.

Question: 4

\$\${18 × 14 - 6 × 8}/{488 ÷ 4 - 20}\$\$ = ?

(A) 1

(B) 2

(C) 3

(D) 4

Ans: B

Given expression = \$\${252 - 48} / {122 - 20}\$\$ = \$\${204}/{102}\$\$ = 2.

Question: 5

The value of 1 + \$\${1}/{4 × 3} + {1}/{4 × 3^2} + {1}/{4 × 3^3}\$\$ is

(A) \$\${3}/{2}\$\$

(B) \$\${121}/{108}\$\$

(C) \$\${31}/{2}\$\$

(D) \$\${40}/{2}\$\$

Ans: B

Given expression = \$\${4 × 3^2 + 3^2+ 3 + 1} / {4 × 3^3}\$\$ =\$\${108 + 9 + 3 + 1} / {108}\$\$ = \$\${121}/{108}\$\$.
