Explanation

Let the Cost price of the Chair is X.

SP = X - 25% of X

720 = 0.75X

X = 960

CP = Rs. 960

So, To gain 25%, SP would be

= 960 + 25% of 960 =Rs. 1200

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.
We know that, M1​D1​=M2​D2​
Required time =3035×12​=14 days
Delayed time =(14−13)=1 day
