Arithmetic Reasoning

                          Find no.of balls in Green box


In three coloured boxes - Red, Green and Blue, 108 balls are placed, There are twice as many balls in the green and red boxes combined as there are in the blue box and twice as many in the blue box as there are in the red box. How many balls are there in the green box??
















Options::

A)  18                           B)  36                             C)   45                             D)  54

Answer::Option D

Explanation:: Let R, B. G represents Red, Blue, and Green receptively.

Then  R + G + B = 108 ..(1)
          G + R = 2B  ..(2)
          B = 2R ..(3)
From 2 and 3 we have G + R = 2* 2R = 4R or G = 3R
Putting G = 3R and B = 2R in 1 we get

R + 2R + 3R = 108 by that we get R = 18

Therefore no.of balls in Green box is 3 * 18 = 54.

Answer  Option 4













Such cubes are related to the corners of the cuboid. Since the number of corners of the cuboid is 4.
Hence, the number of such small cubes is 4.

Triangle Puzzle


Find the number of triangles in below figure??



Answer :: Option D-14











The simplest triangles are ABJ, ACJ, BDH, DHF, CIE and GIE i.e. 6 in number.
The triangles composed of two components each are ABC, BDF, CEG, BHJ, JHK, JKI and CJI i.e. 7 in number.
