Question
A’s age is 150% of what he was 3 years ago, But 75% of
what it will be after 3 years. What is his present age?Solution
Let present age of A be x years. => 150% of (x - 3) = 75% of (x + 3) => 2(x - 3) = (x + 3) => 2x – 6 = x + 3 => x = 9 years
342 – 232 + 256 – 104 = ?
(1/2) – (3/5) + 3(1/3) = ? + (5/6)
666(2/3)% of 30 - 116(2/3)% of 90 =?
((9.77)0- 〖(0.1)〗(-1))/(〖(6/24 )〗(-1) ×(3/2)3+ 〖((-2)/6)〗(-1) ) = ?
...(〖(0.4)〗^(1/3) × 〖(1/64)〗^(1/4) × 〖16〗^(1/6) × 〖(0.256)〗^(2/3))/(〖(0.16)〗^(2/3) × 4^(-1/2) ×〖1024〗^(-1/4) ) = ?
Simplify the expression:
(9x² - 25) / (3x + 5)
30% of 750 + ?% of 400 = 25% of 1016 + 3
41.66% of 888 + 66.66% of 1176 = ?2 - 4√ 16
What value should come in place of the question mark (?) in the following question?
20% of 1500 – 75% of 200 = 125% of ?
√( (664+ √(136+ √(59+ √(21+ √(7+ √81) ) ) ) ) ) = ?
