Question 1
1 / -0

The side of a cube is \(5 cm\). Find the volume of the cube.

A
\(129 cm ^{3}\)

B
\(121 cm ^{3}\)

C
\(125 cm ^{3}\)

D
\(120 cm ^{3}\)

Solution

Given,
Side \((a)=5 cm\)
As we know,
Volume of cube \(=a^{3}\) where \(a=\) side of the cube
\(=5^{3}\)
\(=125 cm ^{3}\)
Hence, the correct option is (C).
Question 2
1 / -0

Direction: What approximate value will come in place of the question mark (?).

\(3.2 \times 8.1+3185 \div 4.95=?\)

A
\(661\)

B
\(560\)

C
\(465\)

D
\(790\)

Solution

Given,

\(3.2 \times 8.1+3185 \div 4.95=? \)

\(\Rightarrow 3 \times 8+3185 \div 5=? \)

\(\Rightarrow ?=24+637 \)

\(\Rightarrow ?=661\)

Hence, the correct option is (A).
Question 3
1 / -0

Direction: What approximate value will come in place of the question mark (?).

\(6789.97-4895.01+1055.99=?+2309.99\)

A
\(641\)

B
\(649\)

C
\(610\)

D
\(750\)

Solution

Given,

\(6789.97-4895.01+1055.99=?+2309.99\)

\(\Rightarrow 6790-4895+1056=?+2310 \)

\(\Rightarrow 1895+1056=?+2310 \)

\(\Rightarrow 2951=?+2310 \)

\(\Rightarrow ?=2951-2310 \)

\(\Rightarrow ?=641\)

Hence, the correct option is (A).
Question 4
1 / -0

Convert \(\frac{14}{40}\) into percentage.

A
\(0.35 \%\)

B
\(3.5 \%\)

C
\(35 \%\)

D
\(350 \%\)

Solution

The fraction in percentage equals:
\(\frac{14}{40} \times 100 \)
\(=\frac{14}{2} \times 5 \)
\(=35 \%\)
Hence, the correct option is (C).
Question 5
1 / -0

The speed of an auto ricksaw is \(40 km / hr\). It travels for \(3\) hours. What is the distance travelled by it?

A
\(120 km\)

B
\(171 km\)

C
\(11.6 km\)

D
\(14.6 km\)

Solution

Given,
The speed of an auto ricksaw \(=40 km / hr\)
Time \(=3\) hours
As we know,
Distance \(=\) speed \(\times\) time
\(=40 \times 3 \)
\(=120 km / hr\)
Hence, the correct option is (A).
Question 6
1 / -0

Simplify \(16-2 \div 7+6 \times 2\).

A
\(27 \frac{5}{7}\)

B
\(27 \frac{2}{9}\)

C
\(27 \frac{1}{7}\)

D
\(27 \frac{2}{7}\)

Solution

Given,
\(16-2 \div 7+6 \times 2 \)
\(=16-\frac{2}{7}+6 \times 2 \)
\(=16-\frac{2}{7}+12 \)
\(=28-\frac{2}{7} \)
\(=\frac{196-2}{7} \)
\(=\frac{194}{7} \)
\(=27 \frac{5}{7}\)
Hence, the correct option is (A).
Question 7
1 / -0

An aeroplane travelled \(4320 km\) in \(6 hrs\). find its speed.

A
\(200 km / hr\)

B
\(300 km / hr\)

C
\(720 km / hr\)

D
None of these

Solution

Given,
Distance travelled by aeroplane \(=4320 km\)
Time \(=6\) hrs
As we know,
Speed \(=\frac{\text { distance }}{\text { time }} \)
\(=\frac{4320}{6} \)
\(=720 km / hr\)
Hence, the correct option is (C).
Question 8
1 / -0

Simplify \(20-[28 \div\{34-(36-18 \div 9 \times 8)\}]\).

A
\(9\)

B
\(5\)

C
\(16\)

D
\(18\)

Solution

Given,
\(\begin{array}{l}
20-[28 \div\{34-(36-18 \div 9 \times 8)\}] \\
=20-[28 \div\{34-(36-2 \times 8)\}] \\
=20-[28 \div\{34-(36-16)\}] \\
=20-[28 \div\{34-20\}] \\
=20-[28 \div 14] \\
=20-2 \\
=18
\end{array}\)
Hence, the correct option is (D).
Question 9
1 / -0

The length of cube is \(20 cm\), then its volume \(\left( cm ^{3}\right)\) is:

A
\(6000 cm ^{3}\)

B
\(8000 cm ^{3}\)

C
\(7069 cm ^{3}\)

D
\(5000 cm ^{3}\)

Solution

Given,
Length of cube \((a)=20 cm\)
As we known,
Volume of cube \(=(a)^{3}\)
\(=(20)^{3}\)
\(=8000 cm ^{3}\)
So, the volume of cube is \(8000 cm ^{3}\).
Hence, the correct option is (B).
Question 10
1 / -0

Convert into percentage \(\frac{24}{288}\).

A
\(8 \frac{1}{3} \%\)

B
\(9 \frac{1}{3} \%\)

C
\(6 \frac{1}{3} \%\)

D
\(7 \frac{1}{3} \%\)

Solution

The fraction in percentage equals:
\(\frac{24}{288} \times 100\)
\(=\frac{1}{12} \times 100\)
\(=\frac{100}{12}\)
\(=\frac{25}{3}\)
\(=8 \frac{1}{3} \%\)
Hence, the correct option is (A).
