Find the odd man out.
331, 482, 551, 263, 383, 362, 284
In each number except 383, the product of first and third digits is the middle one.
Two numbers are respectively 20% and 50% more than a third number. The ratio of the two numbers is:
Let the third number be x. Then, first number = 120% of x =120x/100 = 6x/5
Second number =150% of x = 150x/100 = 3x/2 Ratio of first two numbers = 6x/5 : 3x/2 = 12x : 15x = 4 : 5
Find the unit place digit in the expression (159)144 + (114)123 - (110)510 + (213)25
Find out the wrong number in the given sequence of numbers.
56, 72, 90, 110, 132, 150
The numbers are 7 x 8, 8 x 9, 9 x 10, 10 x 11, 11 x 12, 12 x 13.
So, 150 is wrong.
What is the value of 6x2 - 5y26x2 + 5y2, if x = 13 and y = 15?
Insert the missing number.
2, 6, 12, 20, 30, 42, 56, (....)
The pattern is 1 x 2, 2 x 3, 3 x 4, 4 x 5, 5 x 6, 6 x 7, 7 x 8.
So, the next number is 8 x 9 = 72.
