Re: 10 second questions

Hi ganesh;

Okay, thanks!


In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
A number by itself is useful, but it is far more useful to know how accurate or certain that number is.

Re: 10 second questions

Hi bobbym,

The solutions #4799 and #4800 are correct. Awesome!

#4801. Of two numbers, 4 times the smaller one is less than 3 times the larger one by 5. If the sum of the numbers is larger than 6 times their difference by 6, find the two numbers.

#4802. The ratio of a two-digit number and the sum of the digits of the number is 4:1. If the digit in the unit's place is 3 more than the digit in the ten's place, what is the number?

Re: 10 second questions

Lots of them, if I do not make a math mistake then I will make a copy mistake. If you do not make a copy mistake then I will read the question wrong. We can not be perfect.
