No.

The diagonal of a rhombus does.

Draw a parallelogram with one side small and another side quite big
You will notice the difference in angles.

A says total cost of 3 H is 4.77 including tax so we can easily find the cost... let cost be x cost of 3H is 3x 6% tax will make it 6*3x / 100 6*3x / 100 = 4.77 solve for x you have your answer B says cost is less than 6.5 from less you can easily guess that less can be any value so no need to solve...

or both

C even || d odd || both
Insuff




B
(c+2) x (d+4) is even
cd is even

c even || d even || both
Insuff


A+B

A and B alone can easily be ruled out. Noe lets check the fight between C and E Qn says Women:child = 5:2 A says child:men = 5:11 Now need to find a common equation containing all 3 ratios multiply first quation by 5 Women:child = 25:10 multiply second equation by 2 child:men = 10:22 women:child:men...

Yes the OA is correct.

What answer you are getting?


A
z=u
we can not draw any information about x and y
[You can not assume lines to be parrallel]

B
ABCD is a parallelogram
z=x
and
y=u

but no link between x and y

A+B
we can easily conclude that x=y

The qn says
forty percent of the lights that are supposed to be [n]off[/n] are actually on


and you are taking 40% of lights that are supposed to be on

Hope this helps

4 table = 1/4 cup---------------------1

3 tea = 1 table
multiply by 4
12 tea = 4 table------------------2

from 1 and 2

4 table = 1/4 cup = 12 tea
that is
1/4 cup = 12 tea
1 cup = 48 tea
3/8 cup = 48 * 3/ 8 = 18 tea

ans : 18

Second is an easy one h(100) will be 2 * 4 * 6 * 8 .... 100 = 2^50 (1 * 2 * 3 ... 50) = 2^50 * 50! This h(100) will be divisible by all numbers from 1 to 50 adding 1 h(100) + 1 will not be divisible by any number from 1 to 50 hence smallest prime factor will be greater than 50 so answer is E Do let ...
