The sum of two numbers is 25 and their difference is 15. The ratio of the numbers is:
The sum of two numbers is 25 and their difference is 15. The ratio of the numbers is: Let the number be x and y respectively. => x + y = 25 ----- (i) => x - y = 15 ----- (ii) Solving (i) and (ii) we get, => x = 20 and y = 5 Required ratio = 20:5 = 4:1
The value of [(3√2+2) × (3√2-2)] of 13 + 15 is:
25% of 300 + √(?) = 35% of 600 - 15% of 300
√? = 32% of 900 + 48% of 50
75% of 80 + 12% of 600 + 54 = ?
[(11)2- (12)2+ (5)3]2= ?
2856 ÷ 34 = ?% of 240
20% of 10% of 900 + 84/12 = ?2
If x + y + 3 = 0, then find the value of x3 + y3 – 9xy + 9.
8 × 25% of ? = 400
(√ 121 x 41) + (3√343 x √289 ) = ? x 19
