Reema takes 22 minutes to complete one round Mcq Of Ch 2 Maths Class 10 Java while her friend Saina takes 20 minutes to complete the same.
If they both start at the same time and move in the same direction, after how many minutes will they meet again at the starting a b 3. Question 8. Question 9. Question In decimal expansion and representation, which of the following is not a rational numbers: a terminating decimal b terminates after 17 digits c non-terminating repeating d non-terminating non-repeating.
Answer: d non-terminating non-repeating In decimal representation, a rational number is either terminating or a non- terminating but repeating. Answer: a 0 or 1 5. If a non-zero rational number is multiplied to an irrational number, we always get: a an irrational number b a rational number c zero d one. Answer: a an irrational number The product of a rational non-zero and m irrational number is always an irrational number.
If we write 0. Write an irrational number between 2 and 3. The rational number that corresponds to 0. The greatest number which divides 87 and 97, leaving 7 as remainder is : a 10 b 1 c 87 x 97 d The least number, which when divided by 10,14 and 18, leaves remainder 4, is : a b c d The greatest number which divides 17, 28 and 34 leaving remainders 2, 3 and 4 respectively is: a 5 b 24 c 1 d The minimum number of containers required are: a 36 b 18 c 5 d Answer: c 5 For minimum number of containers required, each container should contain the maximum liquid.
Volume of each container should be the HCF of 72 and , which is Answer: c 1 As, 1 is neither prime nor a composite number, thus, required number is the HCF of 1 and x, which is 1.

Answer: d an irrational number which is a natural number, a whole number and also a rational number. Which of the following rational numbers, in decimal form, terminates? The least positive integer divisible by 20 and 24 is a b c d If one of the numbers is 27, then the other number is a b c d The largest number which divides and leaving remainder 6 in each case is a 82 b 95 c 87 d The product of three consecutive integers is divisible by a 5 b 6 c 7 d none of these.
The least number that is divisible by all the numbers from 1 to 8 both inclusive is a b c 8 d The smallest composite number is: a 1 b 2 c Ch 3 Maths Class 10 Mcq 50 3 d 4.
A lemma is an axiom used for proving a other statement b no statement c contradictory statement d none of these. The product of a rational and irrational number is a rational b irrational c both of above d none of above. A number when divided by 61 gives 27 as quotient and 32 as remainder. Two natural numbers whose difference is 66 and the least common multiple is , are: a and 54 b 90 and 24 c and d and The product of a non zero rational and an irrational number is a Always irrational b Always rational c Rational or irrational d One.
The largest number which divides 60 and 75, leaving remainders 8 and 10 respectively, is a b 75 c 65 d The largest number that will divide , and leaving remainders 7, 11 and 15 respectively is a 17 b 11 c 34 d Which number is divisible by 11?
The sum of a rational and an irrational number is a Rational b Irrational c Both a and c d Either a or b.
