Answer: Option A
Explanation:
Units digit in the given product = Units digit of 4 x 8 x 7 x 3
= Units digit of 672
= 2
Place value of 5 in 65231 = 5 x 1000
= 5000
Face value = 5
Required product = 5000 x 5 = 25000
Answer: Option B
(112 x 54)
Answer: Option D
= 584638125
Answer: Option C
4 a 3 | 9 8 4 } ==> a + 8 = b ==> b - a = 8 13 b 7 |
Also, 13 b7 is divisible by 11
(7 + 3) - (b + 1) = (9 - b)
(9 - b) = 0
b = 9
(b = 9 and a = 1) (a + b) = 10.
6 = 3 x 2. Clearly, 5 * 2 is divisible by 2. Replace * by x.
Then, (5 + x + 2) must be divisible by 3. So, x = 2.
(7 + 3) - (b + 1) = (9 - b) (9 - b) = 0 b = 9
(b = 9 and a = 1) (a + b) = 10.
