There are two numbers in the ratio 8:9. if the smaller of the two numbers is increased by 12 and the larger number is reduced by 19 thee the ratio of the two numbers is 5:9.Find the larger number?

(8/9)x*12/19=5/9,sollution multiply 8 with 9 and 9 with 5,so we get 72-45, and same for 12 and 19,we get 27x=108-95,x=13/27,x=1/2.1,largest number =9*1/2.1therfore the largest number is 4.5.

X:y=8:9 this means x is smaller than y(as x = (8/9)y). According to condition x+12/y-19 =5:99x+108 = 5y-95but 9x=8yso, 8y+108 = 5y-953y = -203y= -203/3, which is the larger number.

What is the output of the following C program?Main(){Printf("%c","abcdefgh"[4]);}

- Apr 2nd, 2010
The answer is "e" because the value "abcdefgh" will get one index for each letter as:a=0b=1c=2d=3e=4f=5g=6h=7And since %c is written in question der4 only one letter will be our answer... and is "e" coz its index is 4.

A stamp collector arranges his stamps during his free time. When he arranges his stamps in pairs, there is one stamp left. It is the same when he arranges the stamps in groups of 3, 4, 5 and 6. Now, how many stamps will he be left with when he arranges them in groups of 8?

First take the LCM of given No. and then add remainder that will give the required no. = 61so, divide by 8 get remainder as 5 ans...

Total stamps are the l.c.m of 3,4,5,6 i.e 60 and 1 is the remainder in all the cases.. so the toal stamp is 60+1=61 now deviding 61 with 8 leaves the remainder 5so if he want to make it a group of 8 he ll be having 5 stamps left
