Explanation

63.3 is the correct answer

total number 15 ×64=960 24 was misread as 34 so actual no is 10 more so subtract 10 from 960 which is 960-10 = 950 now divide 950 by total number which is 15 950/15 = 63.33 is correct answer

Explanation

Let's calculate:

√(9) = 3

6 + 3 = 9

√(9) = 3

22 + 3 = 25

√(25) = 5

Explanation

15 men × 20 days = 300 man-days (total work)

Now, with 25 men:

300 man-days ÷ 25 men = 12 days

Explanation

Let the total piece of land that he has be x hectares,

According to question, x/3 hectare land is used for strawberries, x/4 hectare for chesses, 3x/8 hectare for vegetables and 9 hectares for oats,

total land area= x

Therefore,

x = x/3 + x/4 + 3x/8 + 9,

taking x common,

1 = 1/3 + 1/4 + 3/8 + 9/x,

1 – (1/3 + 1/4 + 3/8) = 9/x,

1 – ((8 + 6 + 9)/24) = 9/x,

1 – (23/24) = 9/x,

1/24 = 9/x or x = 216 hectares

x= 4

Explanation

 Let's break down the problem step by step: Initially, the ratios of Mr. A and Mr. B's investments are not given, so let's assume they are A:B. According to the given information, both Mr. A and Mr. B receive a profit of Rs. 5000 each. The new ratio after the profit becomes 18:24. From the given information, we can create an equation based on the ratios and the profit: (A's initial investment) : (B's initial investment) = 18 : 24 (A's initial investment) / (B's initial investment) = 18 / 24 Now, let's represent A's initial investment as 18x and B's initial investment as 24x, where x is a common multiplier. After the profit, the new amounts for Mr. A and Mr. B would be: Mr. A's new amount = A's initial investment + Profit = 18x + Rs. 5000 Mr. B's new amount = B's initial investment + Profit = 24x + Rs. 5000 We are given that the new ratio is 18:24, so: (Mr. A's new amount) : (Mr. B's new amount) = 18 : 24 (18x + Rs. 5000) / (24x + Rs. 5000) = 18 / 24 Cross-multiplying: 18 * (24x + Rs. 5000) = 24 * (18x + Rs. 5000) 432x + 90000 = 432x + 120000 The x terms cancel out, which means that x doesn't affect the equation. This implies that the value of x is not relevant to the final result. Simplifying further: 90000 = 120000

Explanation

120 is the correct answer

2+3+4=9 3/9x360=120

2+3+4=9 3÷9=0.333..... 0.333....*360=120
