Question
P and Q invested in a business with initial investments of
Rs. 1000 and Rs. ‘y’ respectively. Q withdrew his investment after 6 months. If P’s share out of an annual profit of Rs. 6300 was Rs. 4200, find the value of ‘y’.Solution
ATQ,
Ratio of investment of P and Q = 1000 : y
Ratio of profit share = (1000 × 12) : (y × 6) = 12000 : 6y = 2000 : y
So, (2000 / (2000 + y)) × 6300 = 4200
(2000 / (2000 + y)) = 2 / 3
2000 × 3 = 2(2000 + y)
6000 = 4000 + 2y
2y = 2000
y = 1000
So, the value of ‘y’ is Rs. 1000
12.5% of (100 + ?) = 40
2/9 of 5/8 of 3/25 of ? = 40
24 × √? + 4008 ÷ 24 = 40% of 200 + 327
7(1/2) – 3(5/6) = ? − 2(7/12)
280 ÷ 14 + 11 × 12 – 15 × 6 = ?
1550 ÷ 62 + 54.6 x 36 = (? x 10) + (28.5 x 40)
25% of 1000 + 10% of 150 – 22 × ? = 45
√ 729 × 5 – 220 % of 15 + ? = 120% of 160
What will come in the place of question mark (?) in the given expression?
(40% of ? × 43 ) – 232 = 751
180 % of 45 + √144 × 8 = ?2 + 80 % of 70
