An industrial loom weaves 0.128 metres of cloth every second. Approximately, how many seconds will it take for the loom to weave 28 metre of cloth ? | [
"219 seconds",
"115 seconds",
"175 seconds",
"155 seconds"
] | A | Explanation:
Let the time required by x seconds.
Then, More cloth means More time (Direct Proportion)
So,
0.128 : 1 :: 28 : x => x = {\color{Blue} \frac{28\times 1}{0.128}}
=> x = 218.75
So time will be approx 219 seconds

After spending Rs. 5000 on rent, Rs. 1500 on milk, Rs. 4500 on groceries, Rs.2500 On childrens education Rs. 2000 on petrol and Rs. 700 on miscellaneous expenses, Mr. Kishore saved 10% of his monthly salary. How much did he save in Rs. ? | [
"2160",
"1800",
"2350",
"2300"
] | B | Explanation :
Total Exp = 5000+1500+4500+2500+2000+700 = 16200
Exp in % = 100-10 = 90%, 16200 = 90%

For an employee to qualify for early retirement at a certain company, the sum of the employee’s age and years of service must be at least 76, If Sue was K years old when she was hired by the company, what is the minimum age at which she could possibly qualify for early retirement? | [
"(76-K)/2",
"K+38",
"2K+38",
"(76+K)/2"
] | D | Let y be the years of service at the company.
After y years of service, Sue's age will be K + y.
Sue can retire when (K+y) + y = 76
y = (76 - K)/2
Then Sue's age will be K + y = K + (76 - K)/2 = (76+K) / 2
