The ratio of the present ages of Ginni and Binni is 7:3 respectively. Ginni is ‘n’ years older than Binni. If after 5 years, the ratio of the ages of Binni to Ginni is 1:2, then find the value of √ (n+5).
Let the present ages of Ginni and Binni be 7x and 3x respectively. Here, n = 7x – 3x = 4x According to the question, => (7x + 5)/(3x + 5) = 2/1 => x = 5 Now, n = 4x = 20 Required value = √(n+5) = √(20+5) = √25 = 5
?= √(4 × ∛(16 × √(4 × ∛(16 ×…… ∝)) ) )
{(700 ÷ 20) × 40} – 30 × 18 = ?% of 1000
6 × 1.8 × 0.25 × 70 = ? + 9.5
5.45% of 1854 – 37.5% of 1096 = ? – 48% of 630
(3/7 )Of 3360 ÷ 240 + 30 = (?)²
32% of 4080 + 24% of 455 = x% of 4000
[(15)³ × (8)²] ÷ (90 × 6) = ?²
x= √(4 × ∛(16 × √(4 × ∛(16 ×…… ∝)) ) )
1120 / √x = 80 Then x = ?
(26)2 = {(20% of 40% of 18200) ÷ ?} × 1664 ÷ 128
