it seem nobody intrested

[act_naturally1]

plz tell me how many r correct.....

1)Let A has 100 mangoes
then B will have 90 and C will have 80 mangoes
therefore % of mangoes with B more than those with C = (90-80)*100/80=12.5%

2) Net change in prize of sugar = -20+50+(-20)(50)/100=20%
in order to keep the expenditure same she has to reduce her consumption by
100-(100/1.2)= 17.66%

3) 40% of 25 = 10
75% of 60 = 45.
therefore 35 matches has to b played .

4) previous expenditure = 25 kg
let the prize per kg = 4
therefore total cost = 100
prize went up by 25%.......prize per kg = 4.25
if the total expenditure increases by 8% only instead of 25%
therefore total cost =108
consumption = 108/4.25 = 25.4 Kg

2.the price of sugar decreased by 20% & then increased by 50%.by what percentage should a housewife now increse or reduce her consumption so that the expenditure on sugar remains the same.

my ans is
Let price of sugar be 100 then current pice = first 80 & then 120
by % table in pagal neha %tables cons must decrease by 16.66%

3.the indian cricket team played 25 ODI in a particular season in a year & won 40% of their matches.A new coach was brought in who wanted a successs rate of 75% of the matches played by the end of the year.how many minimum matches more should be played so as to achieve a the target

easy way

its a simple alligation problem 4 those who dont knw this is how u approach it

40% u have won till now & have to will 100% matches frm now on till u have won 75% overall

40 100
75
25 35( u cross subtract there fore the ratio is 25:35
=> u have to win next 35 matches.)

4.the price of an item went up by 25% & the family decided to reduce its consumption so that the total expenditure would increse by only 8% as compared to the previous expenditure if 25 kg of the item was consumed previously then how many kg of the item would be consumed now

let it go up by 25% then cons has to dec by 20% to maintain same price
cons = 20 kg but rise of 8% can be absorbed by family so 8% of 20 =1.6
=> consumption = 21.6kg

5. a salesman used to get 8%on the total sales as commission under a new policy he now gets a fixed amount Rs.2000 & 5% commission on any amount of salesabove Rs.10000.the salesman thus got Rs 540 more this month.what were his total sales for this month

.08x+540=.05(x-10000)+2000
.03x+540=2500
.03x=1960
=>arnd 65K

6.the price of an item increased by by the same percentage over the last 4 weeks.If at the beginning it was 512 /gm & in the end it became 1250/gm find the percentage increase everyweek.

x^4 * 512= 1250
find x
ps: is there ne easy way to solve these kinda probs i personally wund not solve it until i dunno ne other probs & that happens all the time

7.the rate of inflation of a country is 600% what would be the cost of an item 4 years from now if its present cost is Rs. 125 & the rate of inflation remained unchanged throughout.

ans is 6^4*125=1296*125

7.the rate of inflation of a country is 600% what would be the cost of an item 4 years from now if its present cost is Rs. 125 & the rate of inflation remained unchanged throughout.

ans is 6^4*125=1296*125

dont u think we have to use C.I in this case??in that case it becomes 7^4 * 125

[sreejithcs]

yeah ,u have to use C.I and tht's the correct answer.............
