Natali [406]

Answer:

Step-by-step explanation:

ok. you said 2000 and 2500 so I'll just solve for both.

this is very simple, mis/mia wants to earn 2000/2500 so let's solve

this can be done two ways. an equation way, or a dividing way. I personally like the dividing way.

2000 divided by 55= 36.36-- so she will have to tune up 37 bicycles

2500 divided by 55= 45.45-- so she will have to tune 46 bicycles. this is because 46 bicycles, times the amount of money == just a little over 2500 so she has reached  her goal

givi [52]

Answer:

Answer is selling price of second horse is Rs 30400.

Step-by-step explanation:

Maulik bought one horse at Rs 40000 and sold it with a gain of 15%

So the selling price of one horse will be 40000+15% of 40000

                                                      = 40000+6000

                                                      = Rs 46000

Second horse is costing Rs 40000 and had suffered a loss of Rs 3600 on selling both so selling price of both will be = 40000×2-3600

                                                                       = 80000-3600

                                                                       = 76400

  Now selling price of second horse will be selling price of both - selling price of first = 76400-46000 = Rs 30400
