Question
If 78% of (A - B) is equal to 26% of 90% of (A + B), then
find the ratio of B to A.Solution
ATQ,
Given
78% of (A - B) = 26% of 90% of (A + B)
Or, 39 × (A - B) = 117 × (A + B) [78% = 39/50, and 26% of 90% = 23.4% = 117/500]
Multiply both sides by 500 to eliminate denominators:
→ 19500 × (A - B) = 117 × (A + B) × 50
→ 19500A - 19500B = 5850A + 5850B
→ 13650A = 25350B
→ A/B = 25350 / 13650 = 13 / 7
So, B/A = 7/13
5/13 × 104 + 1(2/9) × 198 = 133 + ?
What will come in the place of question mark (?) in the given expression?
(24 2 – 16 2 ) + 75% of 40% of 480 = ?
5 + 2 × 3 ÷ (3 × 2) ÷ 4
Find the Value of √(-√3+√(3+8√(7+4√3)))?
- What will come in the place of question mark (?) in the given expression?
35% of 400 - 20% of 300 = (? - 30) X 2 15848 ÷ 4 – 793 × 6 + 3628 = 3 × ?
? = (22% of 25% of 60% of 3000) + 21
What will come in place of the question mark (?) in the following expression?
(320 ÷ 8 + 22) × 4 = 60 + 40% of ?
70 % of 640 + 75 % of 360 - 19 × 12 = ?
24 × ?2 – 11 × 4 = 1900
