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.
