Now use trial and error method. Then x= 4^9



Q2). There are A, B, C, D, E, F students they speak one are more than one of english, itali, french, Spanish, portueges;

C, E has Italian as common language

3 speak portueges

Out of all 1=all speaks 5 Langs, 1= speaks 4 Langs, 1= speaks 3

Langs, 1= speaks 2 Langs,1= speaks 1 language? (8 marks)

Q4) There was a cycle race going on. 1/5th of the those in front of a person and 5/6th of those behind him gives the total number of participants. How many people took part in the race? (3 marks) Ans : 31 (5 marks)



Approach:

Let the total number of participants be X

So, [(x-1)/5 + 5(x-1)/6] = X







Q5) A man starts from XYZ city and drives a constant speed. After some time he sees a milestone with two digits written on it. after he drives for an hour, he sees another milestone with the same digits, but in reversed order. After another hour of journey, he sees another milestone with original digits but with a zero between them.

What was the speed of his car if milestones show kilometers? ( 6 marks)





Ans ) 45 kmph

Let speed of car be x kmph

Let at first he sees digits as ‘ab’…that is the value of number is: 10a+b

After traveling for one hour, he sees the number as ‘ba’…thus its value is 10b+a

After traveling another hour,he sees the number as ‘a0b’…thus value is 100a+b



Now,

10a+b+x=10b+a..which gives x=9b-9a

10b+a+x=100a+b..which gives x=99a-9b



Equating we get,

b=6a

since ‘a’ and ‘b’ are digits, a=1 and b=6 and thus x=45



Q6). Uncle Reuben and Aunt Cynthia came to town for shopping. Reuben bought a suit and hat for $15. Cynthia paid as much as for her hat as Reuben did for his suit then she spent the rest of their money for a new dress.

On the way home Cynthia called Reuben’s attention to the fact that his hat cost $1 more than her dress, then she added “if we had divided our hat money differently so that we bought different hats mine costing 1 and 1/2 time cost of yours” then we each would have spent the same amount of money.

In that case Uncle Reuben asked "how much would my hat have cost" (6 marks)

Ans). Uncles hat costs $9 (total money was $29)(not sure)check it

9. THIS IS A TOUGH ONE BUT I MANAGED TO GET THE ANSWER.
there are a number of cuffs and collar pieces which belong to freddy and charlie. there total is 30. freddy and charlie give all of tem to the laundry. freddy collects half the number of cuffs and one-third the number of collars and pays his share of 27 cents. 4cuffs costs 5collars.now tell how much did charlie pay for his share?

solution:: let the TOTAL number of the cuffs be X
let the TOTAL number of the COLLARS BE be 30-X

NOW FREDDY COLLECTS 1/2*X + 1/3*(30-X) = X/6 + 10
so charlie would collect 1/2*X + 2/3*(30-X) = -X/6 + 20


by inspection and trial and error we can see that X=12 ((( there is no other way)))

now putting X=12 in first equation we get 12 and puttin in eqn 2 we get 18
there fore freddy pays 27cents for 12 pieces
so charlie will pay ____ cents for his 18 pieces

THE ANSWER WILL BE 40.5 CENTS

10. Y X
Z Y I DON' REMEMBER THE FULL QN, BUT THE QN WAS TO FIND VALUES
