Question
Vijay can do a piece of work in 22 days and Sanjay can
do the same work in 33 days. If Vijay works for 5 days and got Rs. 1650, and the remaining work will completed by Sanjay, then how much rupee Sanjay earned?Solution
Assume total work = LCM (22, 33) = 66 If the entire work is 66 units, Vijay can complete 3 unit per day, and Sanjay can complete 2 unit per days In 5 days, Vijay completes 15 units and got Rs.1650 i.e. Rs.110 per unit. Remaining work = (66 – 15)unit = 51 unit ∴ Sanjay earning = Rs.51 × 110 = Rs. 5610
808 ÷ (128)1/7 + 482 = 4 × ? + 846
17.8 + 3/7 of 89.6 = ?
What will come in place of (?) question mark in the following expression.
5(1/4) + 3(1/2) - 2(1/8) = ?
Simplify the following expressions and choose the correct option.
2500 ÷ (5²) + 60% of 240 = ?
(5/8) x 320 + 100 = ?% of 200 + 90
? % of 1200 = 20% of 30% of 3600
√ 729 × 5 – 220 % of 15 + ? = 120% of 160
(560 ÷ 32) × (720 ÷ 48) = ?
