Verified by Experts

The correct Answer is:
B
पूरे सौदे पर 20% के लिए विक्रयमूल्य
`= ( 450 xx 120)/(100)`
= ₹ 540
`(1)/(3)` भाग का विक्रय मूल्य ` = ( 450)/( 3) xx (90)/(100 = ` ₹ 135
शेष `(2)/(3)` भाग का विक्रयमूल्य `= 450 xx (2)/(3) =` ₹ 300
शेष `(2)/(3)` भाग का विक्रयमूल्य `= 540 - 135 = `₹405
अभीष्ट % लाभ =` (405 - 300)/(300) xx 100 = ( 104)/(3) = 35 %`
