Answer: 17
Explanation The pattern in the series is adding 3 to each number to get the next number, so: 2 + 3 = 5 5 + 3 = 8 8 + 3 = 11 11 + 3 = 14 14 + 3 = 17 So, the correct answer is: 17
Answer: 69
Explanation The pattern involves differences between consecutive terms: 9 - 7 = 2 13 - 9 = 4 21 - 13 = 8 37 - 21 = 16 The differences follow a sequence: 2, 4, 8, 16... (doubling each time). Next difference = 16 × 2 = 32. Next term = 37 + 32 = 69 .
Answer: 120
Explanation The sequence shows factorials: 1!, 1!, 2!, 3!, 4!, so next is 5! = 120 .
Answer: 17
Explanation Let the number x, added 3, then doubled the sum = 40 40 - 6 = 34 34 divided by 2 = 17
Answer: 41
Explanation Step 1: Find the differences between consecutive terms 21 − 20 = 1 23 − 21 = 2 26 − 23 = 3 30 − 26 = 4 35 − 30 = 5 So the differences increase by 1 each time : 1, 2, 3, 4, 5, … Step 2: Find the next difference Next difference = 6 Step 3: Find the next term Next term = 35 + 6 = 41
Answer: R = 11
Explanation Letters decrease by 2 in alphabetical order: Z → X → V → T → R Numbers increase by 2: 3 → 5 → 7 → 9 → 11
Answer: Rs. 2700
Explanation Let Cost Price was X. X + 14% of X = 2850 X + 14X100 = 2850 X + 0.14X = 2850 1.14X = 2850 X = 2500. So, Cost Price = Rs . 2500. Now, Selling Price When profit remains at 8%, = 2500 + 8% of 2500 = Rs . 2700. Short-Cut CP of bicycle = 100114 × 2850 = Rs . 2500 SP for a profit of 8% = 108100 × 2500 = Rs . 2700 S.P=Rs.2850 at 14% Profit is reduced to 8% then the Selling price will be? Solution At first,we have to find actual C.P According to Formula=S.P*100 /100(if profit then add and if loss then minus from 100 =2850*100/100(14%profit will be 114) Then 2850*100/114 C.P=Rs.2500 Now we know that C.P is Rs.2500 ,Profit =8% here we have to find the S.P According to Formula S.P=C.P*100(if profit add and if loss minus from 100/100 2500*108/100 Rs.2700 Answer.
Answer: 2
Explanation Series: 4, 3.5, 3, 2.5, ___ Step 1: Find the pattern 3.5 − 4 = −0.5 3 − 3.5 = −0.5 2.5 − 3 = −0.5 The series decreases by 0.5 each time. Step 2: Find the next term Next number = 2.5 − 0.5 = 2
Answer: 0.48
Explanation 24 % of 2 Let 24 % of 2 = x 24 * 1/100 * 2 = x 48/100 = x 12/25 = x x = 12/25 = 0.48
Answer: 80
Explanation - 179 → 146 → 113 Difference between terms: - 179 - 146 = 33 - 146 - 113 = 33 So, it's decreasing by 33 each time. Next number = 113 - 3 3 = 80
