Verify mobile number to view the solution
48 × 8 = 384 384 × 4 = 1536 1536 × 2 = 3072
4, 29, 149, 599, 1799, ?
4 × 6 + 5 = 29 29 × 5 + 4 = 149 149 × 4 + 3 = 599 599 × 3 + 2 = 1799 1799 × 2 + 1 = 3599
In each of the following questions, a number series is given. Identify the wrong number in the series.
71, 113, 64, 121, 56, 129
alternate series- 71 – 7 = 64; 64 – 7 = 57 113 + 8 = 121; 121 + 8= 129
In each of these questions two equations (I) and (II) are given. You have to solve both the equation and give answer
I. 3m2 − 5m − 28 = 0
II. 2n2 − 17n + 36 = 0
I. 12m2 + 25m + 12 = 0
II. 4n2 − 5n − 6 = 0
What should come in place of question mark (?) in the following questions?
√841 − 99 + 73 = ? ? = 29 - 99 + 73 = 3
392 − 47 × 26 − 26% of 460 = ?
1521 – 1222 – 119.6= 179.4
A shopkeeper sell his goods at 35% loss but he uses false weight of 40%. Find the loss or profit of shopkeeper in this whole process?
Let the cost price of 1kg of Quantity be Rs x Loss = 35% Selling Price = 0.65x But, the quantity sold = 0.6kg Actual Cost Price = 0.6x Profit = 0.65x - 0.6x = 0.05x
32 men were employed to do a work in 40 days. After 27 days, 5 more men were employed for the same work, the work was completed 1 day earlier. If 5 more men were not worked then,approx how many days took in delay?
32 Men x 27 days = 864
37 Men x 12 Days = 444
Total = 864 + 444 = 1308
Now, 1308/32 = 41 days approx
= 1 day delay
