Explanation

=2 % of 6,75,00,000

=2/100 x6,75,00,000

= Rs 1350000

Explanation

By using Flip rule:

So,

A’s 1 day work = 1/10

B’s 1 day work = 1/15

(A+B)’s 1 day work =

(1/10+1/15)= (3 + 2)/30 = 5/30= 1/6 

So together they can complete work in 6 days

Explanation

Mean weight of 6 boys =48 kg.

Let the weight of the 6th boy be a kg.

650+45+50+42+40+a​=48

=>227+a=288=>a=61

weight of the 6th boy =61 kg.

Explanation

Side of a square is increased by 25 % 

Let the  initial side be x

Initial area =x2

New Side =x+4x​=45x​

New area =1625x2​

increase in area =169x2​

∴ % increase =16900​=56.25 %

Explanation

Let the triangle be ΔABC

The sum of angles in triangle is 180∘

 45∘+60∘+∠C=180∘∠C=180−45−60∠C=75∘

Explanation

Given the base of a right angled triangle is 8 m and its hypotenuse is 10 m

Then height =(10)2−(8)2​=100−64​=36​=6 cm

Then area of triangle =21​×8×6=24 sq cm

Explanation

35 men completed the remaining job in 12 days.
Now the same job has to be done by 30 men.
