Answer:
Mr mehra's salary is 26250
Step-by-step explanation:
suppose,
Mr mehra's salary is x
so,
He spends in food = 30% of x
=(30/100) . x [x%=x/100]
= 30x/100
=3x/10
He spends in charity =10% of x
=10x/100
=x/10
Money left = 15750
so,
x = 3x/10 + x/10 + 15750
⇒x - 3x/10 - x/10 = 15750
⇒(10x-3x-x) /10 = 15750
⇒6x/10 = 15750
⇒6x=157500
⇒x = 157500/6
⇒x = 26250
∴Mr mehra's salary is 26250
Philip rides to school in 6 2/5 minutes.....it takes Joey 4 1/2 times as long...
4 1/2 * 6 2/5 =
9/2 * 32/5 =
144/5 =
28 4/5 minutes <== Joey's time to get to school
I'd have to say it's A. Please don't blame me if I'm wrong. :)
