Question
Solution
Alternate Method :
Product = 20 × 21 × 22 × ........ × 40 .
So we can find number of zeroes in 40! then we can subtract number of zeroes in 19! .
So 40/5 = 8 and 8/5 = 1 and adding all quoitent, number of zeroes = 8+1= 9;
19/5 = 3, so number of zeroes in 19! = 3.
So number of zeroes in the given product = 20 × 21 × 22 × ........ × 40 = 9 - 3 = 6.
What should come in place of (?) question mark in the given expression.
(576 ÷ 12) + (3³ × 4) = ?
- 60% of 180 – 30% of 60 = 15% of ?
What will come in the place of question mark (?) in the given expression?
(252 + 198) ÷ ? + 126 ÷ 3 = 144 ÷ 2
- Find the simplified value of following expression:
0.998 + 0.882 + 0.12 √529 + √64 + 92 = ?
What will come in the place of question mark (?) in the given expression?
? = (20 × 62 – 342 )
What will come in the place of question mark (?) in the given expression?
(√1024 + √324)% of 780 = ?% of 260
15848 ÷ 4 – 793 × 6 + 3628 = 3 × ?
{(5/8) + (4/5)} × (?/19) = 33
