(1056/23) givess remainder 21 21 + 2 = 23, So we need to add 2
One side of rectangular field is 15 meter and one of its diagonals is 17 meters. Then find the area of the field.
We know h^{2} = b^{2} + h^{2}
= 8 meter
Area = Length x Breadth
= 15 x 8 m^{2} = 120m^{2}
₹120 are divided among A, B, C such that A’s share is ₹ 20 more than B’s and ₹ 20 less than C’s. What is B’s share?
Let C = x. Then A = (x  20) and B = (x  40).
x + x  20 + x  40 = 120 Or x = 60.
A : B : C = 40 : 20 : 60 = 2 : 1 : 3.
B’s share = ? 120 x (1/6) = ₹ 20
ABCD is a rhombus with diagonals AC and BD.Then, which one among the following is correct?
AC and BD bisect each other and perpendicular to each other. ABCD is a rhombus.
Therefore, AB = BC = CD = DA
And diagonals bisect each other at right angles.
Three numbers are in the ratio 1:2:3. It the sum of their cubes is 98784, then the numbers are
Let the numbers be x, 2x, 3x.
Then (x)^{3} +(2x)^{3} + (3x)^{3} = 98784
x^{3} + 8x^{3 }+ 27x^{3} = 98784
36x^{3} = 98784
x^{3} = 2744
Hence the numbers are 14,28,42

Directions: Select the related word/letter/ number from the given alternatives.
64 : 100 : : 16 : ?
The pattern is:
64 = (8)^{2}
100 = (8 + 2)^{2} = (10)^{2}
16 = (4)^{2}
36 = (4 + 2)^{2} = (6)^{2}
