Question

. The ratio of Richa's salary to Padma's salary was 4:5. Then Richa got an increment of 5% and
Padma borrowed that increased amount from her at the rate of 8% simple interest yearly. If
Padma's salary is 40000 per month, find the amount that Padma will have to return to Richa
after 1 year.​

Answer 1

Given: AB || CD and AD || BC

To Prove: ∠ADC = ∠ABC

Proof: Since AB || CD and AD is a transversal. So sum of consecutive interior angles is 180o.

⇒ ∠BAD + ∠ADC = 180o ….(i)

Also, AD || BC and AB is transversal.

So, ∠BAD + ∠ABC = 180o ….(ii)

From (i) and (ii) we get:

∠BAD + ∠ADC = ∠BAD + ∠ABC

⇒ ∠ADC = ∠ABC (Proved)
