Correct Answer: 31 cm
Explanation:
Required measure = HCF of 403, 434 and 465 = 31 cm
Correct Answer: 7 m
Explanation:
Length of to the rope = Radius of circle
According to the question,
?r2 = 154
? r2 = 154 x (7/22) = 7 x 7 = 49
? r = ?49 = 7 m
Correct Answer: ? 530
Explanation:
Let CP = x
According to the question,
625 - x = x - 435
? 2x = 1060
? x = 1060/2 = ? 530
Correct Answer: 5
Explanation:
Let us assume the first term is a and common difference is d.
Formula for nth term of Arithmetic Progression = a + ( n - 1 ) x d
So first term t1 = a + ( n - 1 ) x d
t1 = a + (1 - 1) x d = a + 0 x d = a
Fifth term t5 = a + ( n - 1 ) x d = a + (5 - 1) x d = a + 4d
According to question,
Sum of the first term and the fifth term = 10
t1 + t5 = 10
? a + a + 4d = 10
? 2a + 4d = 10
? a + 2d = 5.............................(1)
Formula of sum of n terms for Arithmetic Progression,
Sn = n/2[ 2a + ( n - 1 ) x d ]
Put the value of n = 10, Since total number of terms is 10 .
? S10 = 10/2[ 2a + ( 10 - 1 ) x d ]
? S10 = 5[ 2a + 9 x d ] = 10a + 45d
Again According to question,
The sum of all terms of the Arithmetic Progression, except for the 1st term = 99
S10 - first term = 99
? 10a + 45d - a = 99
? 9a +45d = 99
? a + 5d = 11.................................(2)
Subtracts Equation (1) from Equation (2), we will get,
? a + 5d - a - 2d = 11 - 5
? 3d = 6
? d = 2
Put the value of d in equation (1), we will get
? a + 2 x 2 = 5
? a + 4 = 5
? a = 5 - 4
? a = 1
Since tn = a + ( n - 1) x d
find the third term by putting the value of a , n and d. we will get,
t3 = 1 + ( 3 - 1) x 2 = 1 + 2 x 2 = 1 + 4 = 5
So 3rd term of Arithmetic Progression is 5.
Correct Answer: 84, 96
Explanation:
The difference of requisite number must be 12 and each one must be divisible by 12, so the numbers are 84, 96.
Correct Answer: 21
Explanation:
The largest number is the H.C.F. of 210, 315, 147, and 168, which is 21.
Correct Answer: 65
Explanation:
Suppose there are 8y questions were asked apart from the 41 question.Then
37 + 5y/41 + 8y = 80% = 4/5
? 185 + 25y = 164 + 32y
? 7y = 21
? y = 3
? Total no. of questions = 41 + 8 x 3 = 65.
Correct Answer: 25%
Explanation:
Given, a = 20%
Required percentage = [a/(100 - a)] x 100%
= [20/(100 - 20)] x 100%
= (20/80) x 100%
= 25%
Correct Answer: Rs. 18000
Explanation:
? 5% of A=15% of B and 10% of B = 20% of C
? A/20 = 3B/20 and B/10 = C/5
? B = 2C
? A/20 = (3/20) x 2C = 3C/10 =(3/10) x 2000 = 600
? A = (600 x 20) = 12000,
B = (2 x 2000) = 4000
? A + B + C = (12000 + 4000 + 2000) = 18000
Correct Answer: 16 days
Explanation:
( A + B) 's 1 days work = 1/8
B's 1 days work = 1/12
? A's 1 day's work = (1/8) - (1/12) = (3 - 2)/24 = 1/24
? A can complete the work in 24 days
Now, B's 4 days work = 4/12 = 1/3
Remaining work = 1 - 1/3 = 2/3
As, time taken by A to complete the work is 24 days.
? Time taken by A to do 2/3 of the work = 2/3 x 24 = 16 days
