be simplified first. : If an expression contains ‘ then
, multiplication, division, addition and subtraction,
should be performed first then followed by multiplication or division.
Proceeding from left to right, addition and subtraction are carried out in the order in which the sign of addition and subtraction are given.
From the above question if we know the square value of 21 2, then this question will be easily solved 212 = 441 441/49= 9 9 6 = 54 Hence the answer for above series is
: Know the values of 60% =0.6 and 25 % = 0.25 : Now directly multiply 0.6 ×250 + 0.25×600 0.6×250= 150 0.25×600=150 : 150+ 150 = 300 Hence the answer for above series is
2×(3/5) × 8×(1/3) = (13/5) × (25/3) = 65/3
+ 7 ½ ×2×(2/3)= 43/6 × 12/5 = 86/5 65/3 + 86/5 = 38 ×(15/13) hence the answer for above series is
www.ibpsguide.com 19×(3/5) + 23×(2/3) – 24×(1/5) Take all the whole number outside the bracket i.e. 19+23 -24 = 18 Add fractions within bracket 18 ×[(3/5) + (2/3) – (1/5)] = 18(16/15) Hence the answer for above series is
