Answer:
561 Rs.
Step-by-step explanation:
If we let the price of the phone A to be x and the price of the phone B to be taken as y. So, the price of the phone B will be y = x + 20/100x which on solving we will get that y =(120/100)x.
Again from the question we will get that price of the mobile C is y - 10/100y which on solving we will get that (90/100)y which will be equal to 520+x.
So substituting the value of y in the above equation we will get that 90/100*120/100*520 will be equal to approximately 561 Rs.
