"1.903",
"6.487",

"$14",
"$4.4",
"$1.2",
"$5.4"
] | D | Sale Price(SP) = 81 + Markup(MP)
--> Mp = SP-81
and given MP=SP/4 ( 25% is 1/4th)
so SP/4= SP-81
3SP/4= 81
SP=108
Now a discount of 20% is given so NEW SP is .8 *108 =86.4
Profit=86.4-81 =5.4$

A and B together have Sterling 1250. If 4/15 of A's amount is equal to 2/5 of B's amount, how much amount does B have? | [
"Sterling 484",
"Sterling 500",
"None",
"Sterling 460"

A = (2/5 x 15/4)B
A = 3/2 B
A/B = 3/2
A : B = 3 : 2.
B's share = Sterling (1250 x 2/5) = Sterling 500.

A pool can be filled in 4 hours and drained in 5 hours. The valve that fills the pool was opened at 9:00 am and some time later the drain that empties the pool was also opened. If the pool was filled by 9:00 pm and not earlier, when was the drain opened? | [
"at 12:00 pm",
"at 11:00 am",

The combined rate of filling and draining is 1/4 - 1/5 = 1/20.
Let x be the number of hours before the drain was opened.
x/4 + (12-x)/20 = 1
5x + 12 - x = 20
4x = 8
x = 2
The answer is 11:00 am.
