Correct Answer: 63650
Explanation:
19657 Let x - 53651 = 9999 33994 Then, x = 9999 + 53651 = 63650 ----- 53651 -----
Correct Answer: 27474
Explanation:
x + 3699 + 1985 - 2047 = 31111
⟹ x + 3699 + 1985 = 31111 + 2047
⟹ x + 5684 = 33158
⟹ x = 33158 - 5684 = 27474.
Correct Answer: 25
Explanation:
Let 250 / √x = 10.
Then √x= 250 / 10 = 25
∴ x = 625
Correct Answer: 2938
Explanation:
