Question
‘A’ can do a piece of work in 15 days. ‘B’ can
do 60% of the same work in 20 days. If they work together for the entire time and get paid Rs.1450, then find the share of ‘A’.Solution
Let the total work be 60 units. (LCM of 15 and 20) Efficiency of A = 60/15 = 4 units/day Efficiency of B = (60/20) × (60/100) = 9/5 units/day Ratio of the efficiency of A : B = 4 : 9/5 = 20:9 Share of A = (20/29) × 1450 = Rs.1000
Determine the value of k such that the points A(2,3), B(4,k), and C(6,-3) lie on the same straight line.
Solve the given equation for ?. Find the approximate value.
(3/5 of 399.78 + 7/9 of 360.15) ÷ (√63.94 + 25% of 383.94) = ?
...[{(√785) % of 449.85}/(35.89 × 7.14 + 849.89 ÷ 5.12 + 199.78% of 41.09)] = ( 1/? )
65.22 of 359.98% + 459.99 ÷ 23.18 = ?
{(23.65 × 35.12) ÷ 6.97} + 179.86 = ? × 14.76
