Correct Answer: 228
Explanation:
Let the given number be A, B, C, D, E, F, G. Then A x 1 + 1, B x 2 + 2, C x 3 + 3, D x 4 + 4, E x 5 + 5, F x 6 + 6 are the required number . Clearly, 228 is wrong.
Correct Answer: 27
Explanation:
Go on multiplying the number by 2 and adding 1 to it to get the next number. So, 27 is wrong.
Correct Answer: 92
Explanation:
Go on dividing by 6, 5, 4, 3, 2, 1 respectively to obtain the next number. Clearly, 92 is wrong.
Correct Answer: 435
Explanation:
Each number is 15 multiplied by a prime number i.e., 15 x 11, 15 x 13, 15 x 17, 15 x 19, 15 x 23. So, the next number is 15 x 29 = 435.
Correct Answer: 40
Explanation:
There are two series (10, 13, 16, 19) and (5, 10, 20, 40)one increasing by 3 and another multiplied by 2.
Correct Answer: 50
Explanation:
The pattern is
12 ,
12 + 22,
12 + 22 + 32,
12 + 22 + 32 + 42,
12 + 22 + 32 + 42 + 52,
12 + 22 + 32 + 42 + 52 + 62 .
But 50 is not of this pattern.
Correct Answer: 5 : 6
Explanation:
Shantanu's 1 day's work = 1/2
Manu's 1 day's work =1/10
Shantanu's share : Manu's share =(1/12) : (1/10)
= (5/60) : (6/60)
= 5 : 6
Correct Answer: 5 : 3
Explanation:
A's 1 day's work = 1/9
B's 1 day's work = 1/15
A's share : B's share = (1/9) : (1/15)
= (5/45) : (3/45)
= 5 : 3
Correct Answer: A = ? 500 and B = ? 400
Explanation:
A' s 1 day's work = 1/8
B' s 1 day's work = 1/10
? A' s share : B' s share
= 1/8 : 1/10 = 5/40 : 4/40 = 5 : 4
Let A' s share = 5k
and B' s share = 4k.
According to the question,
5k + 4k = 900
? 9k = 900
? k = 100
? A' s share = 5k = 5 x 100 = ? 500
and B' s share = 4k = 4 x 100 = ? 400.
Correct Answer: ? 90
Explanation:
A's 1 day's work = 1/3
B's 1 day's work = 1/2
A's share : B's share = 1/3 : 1/2 = 2/6 : 3/6
= 2 : 3
Share of A = (2/5) x 225 = ? 90
