Sign in nowLet the fraction is x/y As per question (x +1 )/(y- 1 ) = 1 x + 1 = y – 1 x-y = - 2 ……………(i) x/(y +7)= 1/4 4x = y+ 7………………(ii) By solving these equations, we get x = 3 Putting the value of x in equation (i), we get 3 – y = -2 – y = - 5 y = 5 So the fraction is 3/5
18, 25, 33, 42, 52, 63, ?
(12% of 1250 + 85% of 400) x 10 = ?2
9999² + 1111² =?
1240 ÷ ? = 242 + 123 – 514 × 4
18 × √225 + 378 ÷ √441 = ? × 9
(190/38) × (55/5) + (306/18) = ?
1024 ÷ 32 = 2(1/2)×?
125% of 129 ÷ 43 × 28 ÷ 7 = ? ÷ √16
