551. Imran made a profit of 20 percent in the first year. Next year he had a loss of 25 percent on the capital he had at the beginning of the second year. What was his overall loss?

Check answer and explanation

Answer: 10 %

Explanation Suppose Imran has x rupees If he gain 20 percent profit After one year rupees = X + 20% of X X + 20X/ 100 = 110X + 20X / 100 120X/100 Now if he has lost 25% on 120X / 100 then Rupees after seconds year = 120X/100 – 25% of 120 X/100 =120X/100 – 25(120X)/10000 = 1200X-3000X/10000 = 1200X-3000X/10000 = 9000X/10000 =9X/10=90X/100=90% OF X Total lost = 100 – 90 =10 X = 10 % of X

554. The sum of the digits of a two-digit number is 15 and the difference between the digits is 3. What is the two-digit number?

Check answer and explanation

Answer: Cannot be determined

Explanation Let the ten's digit be x and unit's digit be y Then, x + y = 15 and x - y = 3 or y - x = 3 Solving x + y = 15 and x - y = 3, we get: x = 9, y = 6 Solving x + y = 15 and y - x = 3, we get: x = 6, y = 9 So, the number is either 96 or 69 Hence, the number cannot be determined.

555. Mr. A and Mr. B invest in ratio with a Rs.5000 profit for each, new ratio becomes 18:24. What is the total amount of Mr. B after profit?

مسٹر اے اور مسٹر بی ہر ایک کے لیے 5000 روپے کے منافع کے ساتھ تناسب میں سرمایہ کاری کرتے ہیں، نیا تناسب 18:24 بن جاتا ہے۔\ منافع کے بعد مسٹر بی کی کل رقم کتنی ہے؟

Check answer and explanation

Answer: Rs.12000

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

556. By selling a bicycle for Rs. 2,850, a shopkeeper gains 14%. If the profit is reduced to 8%, then the selling price will be:

Check answer and explanation

Answer: Rs. 2700

Explanation Let Cost Price was X. X + 14% of X = 2850 X + 14X100 = 2850 X + 0.14X = 2850 1.14X = 2850 X = 2500. So, Cost Price = Rs . 2500. Now, Selling Price When profit remains at 8%, = 2500 + 8% of 2500 = Rs . 2700. Short-Cut CP of bicycle = 100114 × 2850 = Rs . 2500 SP for a profit of 8% = 108100 × 2500 = Rs . 2700 S.P=Rs.2850 at 14% Profit is reduced to 8% then the Selling price will be? Solution At first,we have to find actual C.P According to Formula=S.P*100 /100(if profit then add and if loss then minus from 100 =2850*100/100(14%profit will be 114) Then 2850*100/114 C.P=Rs.2500 Now we know that C.P is Rs.2500 ,Profit =8% here we have to find the S.P According to Formula S.P=C.P*100(if profit add and if loss minus from 100/100 2500*108/100 Rs.2700 Answer.

557. Solve for 2x + 5 = 13

Check answer and explanation

Answer: X = 4

Explanation 2x + 5 = 13 Step 1: Subtract 5 from both sides 2x = 13 - 5 2x = 8 Step 2: Divide both sides by 2 x = 8 / 2 x = 4

558. The angle between the minute hand and the hour hand of a clock when the time is 4:20 is _____?

Check answer and explanation

Answer: 10°

Explanation At 4:20, the hour hand is between 4 and 5. Hour hand angle from 12: 4 × 30° = 120° Additional angle for 20 minutes: (20/60) × 30° = 10° Total hour hand angle: 120° + 10° = 130° Minute hand angle from 12: 20 × 6° = 120° Angle between hour and minute hands: 130° - 120° = 10° Last verified on 22-02-2026

559. if the ratio of two numbers is 5:7 and if 5 subtracted from the sum of these two numbers, 79 obtained, then the numbers are?
