**Solution for yesterday’s problem**

**Conventional method**

Let the cost price of first horse = x; selling price = 1.15x

Let the cost price of second horse = y; selling price = .92y

By supposition, 1.15x = .92y; => x/y = 92/115

Now, divide $1440 with this ratio

1440* (115/207) = $800

**Fastrac method**

1440*(100+% gain of first horse)/(100+%gain of first+100-% loss of second horse)

**Today’s problem**

**If A can do a piece of work in 10 days and along with B can do the same work in 6 days what is the efficiency ratio of A to B? (asked by Preeti)**
