TS Police SI Mains 2018 Arithmetic and Reasoning - Question 125

If $$\triangle$$ denotes addition. $$\Box$$ denotes multiplication, * denotes substraction and $$\triangledown$$ denotes division then $$3 * 4 \Box 5 \triangle 6 \triangledown 2 =$$

Solution

The given expression in standard mathematical operations can be termed as:
3 - 4 x 5 + 6/2
= 3 - 4 x 5 + 3
= 3 - 20 + 3
= -14

TS Police SI Mains 2018 Arithmetic and Reasoning - Question 126

From point P. a man rides a cycle 9 km towards East. Then, he rides the cycle 2 km towards North. From there, he rides the cycle 3 km towards East. Finally he rides the cycle 3 km towards North to a point Q. Then the distance between the points P and Q is (in km)

Solution

Consider P at the origin (0,0)
Then Q is located at (12,6)

Hence, distance between P and Q = $$\sqrt{\ \left(12-0\right)^2+\left(6-0\right)^2}$$ = 13

TS Police SI Mains 2018 Arithmetic and Reasoning - Question 127

A person walks 3 km towards East, then walks 3 km towards South, then walks 7 km towards West and stops. The distance from the starting point and the end pointis (in km)

Solution

Let starting point have co ordinates (0,0)
Then finishing point = (-4, 3)

Distance between starting point and finish point = $$\sqrt{\ \left(-4-0\right)^2+\left(3-0\right)^2}$$ = 5

TS Police SI Mains 2018 Arithmetic and Reasoning - Question 128

(c) 3 lies opposite 5.
Then the true statement(s) among (a), (b), (c) is(are)

Solution

After folding, we get :
2 and 4 opposite each other
