Mix Test - 3

Whole numbers between \(32\) and \(52\) is \(19\).

\( (52−32−1=19)\)

\((33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51)\)

Hence, the correct option is (A).

The sum of \(1.2\) and \(2.3\):

\(= 1.2+2.3\)

\(=3.5\)

Hence, the correct option is (B).

Factors of \(216=2 \times 2 \times 2 \times 3 \times 3 \times 3\)

Factors of \(240=2 \times 2 \times 2 \times 2 \times 3 \times 5\)

LCM \( =2 \times 2 \times 2 \times 2 \times 3 \times 3 \times 3 \times 5=2160\)

Hence, the correct option is (A).

\(1\) multiplied by the number \(82\), gives the same number.

'\(1\)' is the only number that when multiplied to any number gives the same number.

Hence, the correct option is (D).

Proper fraction is a fraction in which the numerator is less than the denominator, for example \(\frac{11}{23}\).

So, \(\frac{11}{23}\) is a proper fraction.

Hence, the correct option is (B).

Given,

Cost price of cycle \(=\) Rs. \(3725\)

Loss \(=\) Rs. \(589\)

As we know,

Selling price \(=\) Cost price \(-\) loss

Selling price of cycle \(=3725-589\)

\(=\) Rs. \(3136\)

Hence, the correct option is (B).

Factor of \( (4160) =2^{6} \times 5^{1} \times 13^{1} \)

\(=(6+1)(1+1)(1+1) \)

\(= 7 \times 2 \times 2 \)

\(= 28\)

Hence, the correct option is (A).
