wow!

@IF INVESTMENT ARE IN THE RATIO OF A:B:C & TIMING OF THEIR INVESTMENT IN THE RATIO OF X:Y:Z ,THEN THE RATIO OF THEIR PROFIT IN AX:BY:CZ.

IF INVESTMENT ARE IN THE RATIO A:B:C,PROFITS IN THE RATIO OF P:Q:R,THEN THEN RATIO OF TIME P/A:Q/B:R/C.

IF THE RATIO OF PERIOD OF THEIR INVESTMENT IN THE RATIO OF T1:T2:T3 AND THEIR PROFIT IN THE RATIO OF P1:P2:P3 THEN THE CAPITAL IN THE RATIO OF
P1/T1:P2/T2:P3/T3

A,B &C are partners A receives 2/5 of profit and B & C share remaing profit equally A's income is increased by 220 when the profit rises from 8% to 10%.find the capital invested by A,B,C

TWO PARTNERS INVEST 125000 AND 85000.60% OF TOTAL PROFIT DIVIDE EQUALLY BETWEEN THEM AND REST PROFIT TREATED INTREST ON CAPITAL. IF ONE PARTNER GET 350 MORE THAN THE OTHER FIND THE TOTAL PROFIT MADE

A and B invested in the ratio of 3:2.if 5%of the total profit goes to charity and A's share is 855,find the total profit
TOTAL PROFIT = 855(100/100-5)(1+2/3)
=855(100/95)(5/3)
=1500

A PUTs 600 more in a business than B ,but B has invested his capital for 5 month while A has invested for 4 month if the share of A is 48 more than that of B out of the total profit of 528 , find the amount invested by A & B

B's profit =( 528-48)/2=240
A's profit = 240+48=288
A'sprofit for one month = 288/4=72
B's profit for one month = 240/5=48
A & B's investment proptional to profit
72:48
3:2
if difference 1 equal to 600
then A's investment = 600×3=1800
B's investment= 600×2=1200

A,B & C CAN DO A WORK IN 20,25& 30 DAYS THEY UNDERTOOK TO FINISH THE WORK TOGETHER FOR 2220, THEN THE SHARE OF A EXCEEDS THAY OF BY,

RATIO OF SHARE's = ratio of 1 days work
1/20:1/25:1/30
=15:12:10
A's share = 2220×15/37=900
B's share =2220×12/37=720
A's share exceed B's share = 900-720=180

A MAN CAN DO A WORK IN 10 DAYS .WITH THE HRLP OF A BOY HE CAN DO THE SAME WORK IN 6 DAYS .IF YHEY GET 50 FOR THAT WORK,WHAT IS SHARE OF BOY?

THE BOY CAN DO THE WORK IN=(10×6)/(10-6)
=15 days
man's share:boy's share
15:10=3:2
MAN's share 30
Boy's share 20
MAN WILL GET 30
BOY WILL GET

A & B UNDERTAKE TO DA A WORK FOR $56.A can do it alone in 7 days and Bcan do it in 8 days .if with the assistance of a boy they finish work in 3 days then the boy will get?

56[1-(7+8)/(7-8)×3]
=$11

A,B & C TOGETHER EARN 1350$ IN 9 DAYS .A & C together earn 470 in 5 days .B & C together earn 760 in 10 days find the daily earning of A,B,C

daily earning C= 760/10+470/5-1350/9
=76+94-150
=20
Daily earning of A =1350/9-760/10
=150-76
=74
DAILY earning if B = 1350/9-470/5
=150-94
=56

A batsmanin his 17th innings make a score of 85 and there by increase his average by 3.what is his average after 17th innings?

85-3(17-1)
=85-3×16
=85-48
#37

A cricketer has complted 10th innings and his average is 21.5.how many run must he make in his next innings so as to raise his average to 24?

10(24-21.5)+24
=10×2.5+24
25+24=49
