Re: 10 second questions

Hi bobbym,

The solution #5077 is correct. Excellent!

Regarding #5078, you are correct. I missed a part of the problem. I am sorry. I have altered the problem:

A trader buys a chair for $600 and sells it for $765 at a credit of 4 months. Reckoning money worth 6% per annum, find is gain percent.

#5079. A property dealer sells a house for $630,000 and in the bargain makes a profit of 5%. Had he sold it for $500,000, then what percentage of loss or gain he would have made?

#5080. A shopkeeper sells one transistor for $840 at a gain of 20% and another one for $960 at a loss of 4%. Find his total gain or loss percent.

The solutions #5091, #5092, and #5093 are correct. Remarkable!

The solution #5094 is correct too, the solution is to be stated: Base : 900 meters, Altitude : 300 meters. Good work!

#5095. Find the length of the altitude of an equilateral triangle of side

centimeters.

#5096. In two triangles, the ratio of the areas is 4:3 and the ratio of their heights is 3:4. Find the ratio of their bases.
