Find out who purchased the machine at maximum price?  Correct Answer Rekha

Let, the MRP of the washing machine be Rs. 100x

In case of Rekha,

Price after 1st discount = Rs. (100x – 100x × 5/100) = Rs. 95x

Price after 2nd discount = Rs. (95x – 95x × 20/100) = Rs. 76x

Price paid by Rekha = Rs. 76x

In case of Hema,

Price after 1st discount = Rs. (100x – 100x × 16/100) = Rs. 84x

Price after 2nd discount = Rs. (84x – 84x × 15/100) = Rs. 71.4x

Price paid by Hema = Rs. 71.4x

In case of Kajal,

Price after 1st discount = Rs. (100x – 100x × 15/100) = Rs. 85x

Price after 2nd discount = Rs. (85x – 85x × 12/100) = Rs. 74.8x

Price paid by Kajal = Rs. 74.8x

Rekha purchased the machine at maximum price.
