​

Answer 1

Answer:

36000rupees

Step-by-step explanation:

CP of Arpita=SP of Ria

SP of Ria =4320 rupees

loss% =10%

CP of Ria = SP*100/100-10%. =4320*100/100-90 =43200 rupees. CP of Ria=SP of Mona.

SP of Mona= 43200 rupees. , P%= 20%

CP of Mona= 43200*100/100+20%. = 36000rupees Hence, answer is 36000 rupees.
