Let the amount be divided into 7x,4x,3x and 2x.
7x-2x = 500 5x=500 x = 100
Total amount = 7x+4x+3x+2x = 16x = Rs.16002758 + 20581 – 17889 = ________?

Explanation:
2578 + 20581 – 17889 = 2600 + 20600 – 18000
= 23200 – 18000 = 5200The speed of a boat in upstream is 60 kmph and the speed of the boat downstream is 80 kmph. Find the speed of the boat in still water and the speed of the stream?
The speed of a boat in upstream is 60 kmph and the speed of the boat downstream is 80 kmph. Find the speed of the boat in still water and the speed of the stream?A. 70, 10 kmph
B. 35, 27 kmph
C. 50, 60 kmph
D. 45, 55 kmph
Explanation:
Speed of the boat in still water = (60+80)/2 = 70 kmph. Speed of the stream = (80-60)/2 = 10 kmph.The speed of a boat in still water is 2km/hr. If its speed upstream be 1km/hr then speed of the stream is________?
The speed of a boat in still water is 2km/hr. If its speed upstream be 1km/hr then speed of the stream is________?A. 1.5km/hr
B. 3km/hr
C. 1km/hr
D. none
Explanation:
Let the speed of stream be x km/hr
Speed upstream = (2-x) km/hr = 2-x = 1 => x = 1 km/hrNine men went to a hotel. Eight of them spent Rs.3 each over their meals and the ninth spent Rs.2 more than the average expenditure of all the nine. Determine the total money spent by them?
Nine men went to a hotel. Eight of them spent Rs.3 each over their meals and the ninth spent Rs.2 more than the average expenditure of all the nine. Determine the total money spent by them?A. Rs.29.25
B. Rs.30.25
C. Rs.32
D. Rs.35
Average of 9 = x
9x = 8 * 3 + x * 2 x = 3.25
Total = 9 * 3.25 = 29.25A shopkeeper buys mangoes at the rate of 4 a rupee and sells them at 3 a rupee. Find his net profit or loss percent?

If he buys 4 a rupee, his CP = 3
He selling at 3 a rupee, his SP = 4
Profit = SP – CP = 4 – 3 = 1
Profit Percent = 1/3 * 100 = 33 1/3 %
