Arithmetical Reasoning Questions

This can be solved in two ways using only 6, 11, 9 and 3 we must get 24.

1. {[(11–6) x 3] + 9}

By solving this we get

5 x 3 + 9 = 15 + 9 = 24.

2. [(9–6) x (11–3)]

= 3 x 8 = 24.

Yes, Every integer is a rational number.  A rational number is a number which can be expressed as a ratio of two integers numerator and denominator where (the denominator not being 0 ).

Hence, Every integer can be expressed in ratio of two integers. 

The Cartesian Product is also an operator which works on two sets. It is sometimes called the CROSS PRODUCT or CROSS JOIN. It combines the tuples of one relation with all the tuples of the other relation.

Number - '79246358' If the digits are arranged in descending order from left to right, new number = 98765432 Difference between the digits which are third from the right and second from the left = 8 - 4 = 4.

Complimentary angles are those two angles whose sum is 90 whereas two angles whose sum is 180 are called Supplementary angles.
