Answer 1

SOLUTION

TO CHOOSE THE CORRECT OPTION

Sonu sold an article for ₹ 3400 and lost 15% on it. The cost price of the article was

(a) ₹ 4400

(b) ₹ 4000

(c) ₹ 3600

(d) ₹ 4200

EVALUATION

Let cost price of the article = ₹ 100x

Since lost is 15%

So loss amount = ₹ 15x

Selling price

= ₹ 100x - ₹ 15x

= ₹ 85x

So by the given condition

85x = 3400

⇒ x = 40

Hence the cost price of the article

= ₹ 100x

= ₹ ( 100 × 40 )

= ₹ 4000

FINAL ANSWER

Hence the correct option is (b) ₹ 4000
