Correct Answer - Option 3 : 5%

Given:

The cost price of television = Rs. 25,000

Profit% of Asha = 20%

Lata spent on repairing = Rs. 5000

Loss% of Lata = 25%

Formulae used:

1.) S.P = C.P × (100 + P%)/100

2.) S.P = C.P × (100 – L%)/100

Where,

S.P → Selling price

C.P → Cost price

P% → Profit%

L% → Loss%

Calculations:

The selling price of Asha = C.P × (100 + P%)/100

⇒ 25,000 × (100 + 20)/100

⇒ Rs. 30,000

The cost price of Lata = Selling price of Asha

The cost price of Lata = 30,000

Lata spent on repairing = Rs. 5000

So, Total cost price of Lata = 30,000 + 5,000

⇒ Rs. 35,000

The selling price of Lata = C.P × (100 – L%)/100

⇒ 35,000 × (100 – 25%)/100

⇒ Rs. 26,250

The cost price of Sarita = Selling price of Lata

The cost price of Sarita = 26,250

The cost price of Sarita more to the cost price of Asha = 26,250 – 25,000

⇒ 1,250

More % = (1,250/25,000) × 100

⇒ 5%

∴ The cost price of Sarita is 5% more than the cost price of Asha.
