• What are integers used for in real life?
What are integers used for in real life?
Integer numbers can be defined as a number with no fractional part. Which means, we can count forward and backward using integers. After rounding fractional numbers up or down to the nearest whole number, what we get is known as Integer. Integers helps in computing efficiency in positive or negative numbers in virtually every field of life. It can be practically used in the real world for Computer Programming and coding. Integer also helps in knowing the position where one is standing. They are two types of Integers known As Positive Integers and Negative Integers. It also helps to calculate how more or less measures to be taken for achieving better results.

The relationship can not be determined from the information given.-ans: (d) (2nd car started 2 hours late, so 1st car would be 2m miles ahead at 15:00 hours. the gap between 2 cars would vary depending upon the difference in speeds of the cars. as per the question, n < 1.4m, let n = 1.35 m distance covered by car a at 21:00 hours = 8 m and distance covered by car b = 6 x 1.35 = 8.1 m so distance covered by car b will be more. let n = 1.3 m distance covered by car b at 21:00 hours = 6 x 1.3 = 7.8 m so distance covered by car a will be more. so for some values, 2nd car would be ahead (1.35m) & for some values (1.3m), 1st car would be ahead. hence the relationship can not be determined from the information given.)

Quantity a is greater.-ans: a (the share in profit will in proportion to the total investment by each. let susan invested \$a initially every month. she would invest \$a every month for 4 months. after 4 months, she would invest (a (�)a) = 3/4 a every month for 4 months. finally, she would invest 3/4 a 1/2 of 3/4 a = 3/8 a. so susans total investment in one year = 4xa + 4x3/4 a + 4x3/8 a = 17/2 a. now lucys contribution = 10 x 0.9 (3/8 a) = 27/8 a. (90% of susans last month contribution (3/8 a)). the share in profit of susan & lucy = (17/2) a : (27/8) a = 68 : 27 ((17/2) a / (27/8) a). hence quantity a is greater.)

T = 18 minutes-2. t = 26 minutes-3. t = 30 minutes-ans: b, d and e (both a & b together can fill up the tank in 18 minutes (1/30 + 1/45 = 1/18) now tap c & d should also be able to empty the tank in not more than 18 minutes for tank to remain at half level. so maximum time taken by d will be 36 minutes. (1/36 + 1/36 = 1/18) now if c & d take less time to empty, then when all tapes are open then the level will go down from 1/2. but tap d is at 1/2 level, so it will stop working and only c will empty in 36 minutes while a & b will fill up in 18 minutes. so water level will go up & when the level is more than 1/2, then d will start working & level will start reducing. ultimately it will settle at 1/2 level only when all tapes are on. this will happen for any value of t < 36 minutes. hence 0 < t < 36 minutes. so t will take any value less than 36 minutes.)
