Question
M and N started a business. M invested Rs. 1600 and N
invested Rs. ‘t’. N withdrew after 6 months. If M received Rs. 5000 out of the total annual profit of Rs. 7500, find the amount invested by N.Solution
ATQ,
Investment ratio = 1600 : t
Profit ratio = (1600 × 12) : (t × 6) = 19200 : 6t = 3200 : t
(3200 / (3200 + t)) × 7500 = 5000
(3200 / (3200 + t)) = 2 / 3
3200 × 3 = 2(3200 + t)
9600 = 6400 + 2t
2t = 3200
t = 1600
So, the value of ‘t’ is Rs. 1600
√3600% of 150 + 3/5 of 360 - ? = 210
52% of 36% of 810 = 72% of 18% of ?
315 ÷ 9 + 23 × 3+ 22 = ?× √441
(560 ÷ 32) × (720 ÷ 48) = ?
What value should come in the place of (?) in the following questions?
30% of 160 – 25% of 240 + 43 = ?
√0.49 + √6.25 + √1.44 + √1.21 =? % of 125
31% of 1900 - ? = 73
4.5 times 5/0.9× 35% of 240 =?
√? = 80% of 720 - 22% of 2500
{(81% of 800 + 28 × 4) – 27 × ?} = 11 × 20
