Question
2, 6, ?, 20, 30,
42 What will come in place of the question mark (?) in the following series?Solution
The given series follows the following pattern: 11 + 1 = 2 22 + 2 = 6 32 + 3 = 12 42 + 4 = 20 52 + 5 = 30 62 + 6 = 42
322 – 182 + 11 × 24 = ?
12% of 450 + 16% of 1500 = ?
What will come in place of the question mark (?) in the following expression?
25% of 2000 – 50% of 500 = 100% of ?
What will come in the place of question mark (?) in the given expression?
? = (20 × 62 – 342 )
The value of {5 − 5 ÷ (10 − 12) × 8 + 9} × 3 + 5 + 5 × 5 ÷ 5 of 5 is:

192.251 + 326.233 + 125.021 + 19.273 = ?
60% of 3050 + 80% of 6050 =?
