Question
94 is divided into two parts in such a way that the
fifth part of the first and the eighth part of the second are in the ratio 3 : 4 The first part is:Solution
Let the first & second parts be p & q respectively. According to the question, (1/5) of first : (1/8) second = 3 : 4 ⇒ (p/5) : (q/8) = 3/4 By using the above concept, ⇒ 8p/5q = 3/4 ⇒ p/q = 15/32 = k (Let) ⇒ p = 15k, q = 32k Since, first part + second part = 94 ⇒ 15k + 32k = 94 47k = 94 or k = 2 Hence, p = 15k = 30 ∴ The first part is 30.
(500 × 6 ÷ 10) - (√256 + 8) = ?
22% of 400 + √ ? = 34% of 800 - 25% of 400
(2/5)(32% of 4500 – 440) = ? × 8
1550 ÷ 62 + 54.6 x 36 = (? x 10) + (28.5 x 40)
What will come in the place of question mark (?) in the given expression?
96 ÷ (9 - 6.6) + 17.5 X 6 = ? ÷ 8
13 X ? = 85 X 4 + √81 + 2
45% of 360 - 160 + ? = √324
((67)32 × (67)-18 / ? = (67)⁸
4567.89 - 567.89 - 678.89 = ?
82.3 × 644.7 × 723.4 × 815.85 = 72?
