Question
Four number pairs are given. In each pair, the number
on the left side of (-) is related to the number on the right side with some Logic/Rule/Relation. Three pairs are similar on the basis of the same logic. Select the odd one out from the given alternatives. [NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits.]Solution
The second number is obtained by multiplying the first number by 3. Option A: 42 x 3 = 126. Option B: 31 x 3 = 93. Option C: 28 x 3 = 84. Option D: 54 x 3 = 162 In the option, the second number is given as 152, which is incorrect according to the rule.
The graphs of the equations 3x-20y-2=0 and 11x-5y +61=0 intersect at P(a,b). What is the value of (a² + b² − ab)/(a² − b²...
If, 4x2 + y2 + 12x + 6y + 18 = 0, then find the value of (2x + y)/(y + 6x).
If 70% of ‘y’ is 25% more than 30% of 140, then value of ‘y’ is:
Simplify:
5x + 7y - [(10x + 4y) - (3x + 2y) + 5y] - 3xWhat is the value of (a² + b²+4c²- ab-2bc-2ca) (a + b+2c):
‘a’ is directly proportional to ‘b’. If at a=30, the value of ‘b’ is 20% greater than ‘a’, then find the value of ‘a’ when b=54.
